Six Ways to Preserve Zucchini

According to my parents, I have been a good eater from day one. My first sentence was, “more mayonnaise, please” and the first thing I learned to spell was “i-c-e-c-r-e-a-m.” Until it got too long, my mom kept a running list in my baby book of the foods I’d eaten and enjoyed. At a year old, my favorite foods were yogurt, bananas, cottage cheese, cheerios and plain steamed zucchini. Thirty-two years later, I still eat every single one of those items with some regularity. And I adore zucchini.

zucchini spread

One of the things I love about zucchini (and really, any other summer squash), is its intense versatility. This time of year, people begin to complain about the influx of squash and how tired of it, but how can you be weary of something that can do so many different things and do them well?

My favorite squash application is one I learned from my friend Lucy, many years ago. You cube up several pounds of zucchini or yellow squash, combine it with olive oil, butter, garlic and a few herbs and cook it down until it has reduced by more than half. What you’re left with is a deeply flavorful, creamy spread. I eat it on toast, serve it at parties and smear it on homemade pizza. It freezes well and does an incredible job at taking a mountain of zucchini and making it feel manageable. Here’s an organized recipe for this spread, that I wrote up for Philly Homegrown last summer.

One thing I hear frequently from new picklers is how disappointed they are with the texture of their water bath processed cucumber pickles. And I can understand this, because I don’t always love the spongy texture that cucumbers can acquire when exposed to heat (these days, I tend to stick mainly to refrigerator pickles when it comes to preserving cucumbers). However, I do like the flavor of a dill pickle come January and so I’ve taken to turning to zucchini instead of the traditional cuke. It holds its texture better and tastes awfully nice.

zucchini with personality

Another way I preserve summer squash is by turning it into a relish. You won’t find the recipe here on the blog because I saved it for the cookbook, but happily, Aimee made it for a piece on Simple Bites a few weeks back, so  you can check it out even if you don’t have my little cookbook. It’s good on hot dogs, tasty with cheesy toast and stirs into tuna salad just as well as the cucumber version does.

curried zucchini pickles

The last pickle pieces I wrote for Serious Eats before hanging up my In a Pickle hat was all about zucchini pickles with curry. This is a tasty and popular way to put up a zucchini abundance for later in the year.

shredded zucchini

Of course, if you’re pressed for time and can’t spare the moments it takes to make even the most simple pickle, shred that summer squash, measure the shreds into two-cup portions and freeze them. You can bake with it, use it in soups or make zucchini fritters when the days are short and chilly.

chocolate zucchini bread

This summer’s favorite zucchini preservation method has been chocolate zucchini bread. I make it so it’s just barely sweet. To serve, I toast up a slice and drizzle just a little bit of honey over top. I have three small loaves in the freezer, ready for a day when I need a bit of a treat. The recipe for that bread is at the bottom of this post.

How do you preserve zucchini and other summer squashes?

MightyNest Giveaway Winner

Yummy food swap items!

I’ve had a couple of breathlessly busy days in the Chicago area and I have one more full day of book stuff up in Lake Forest before I head home and I can wrap my brain around writing a post of substance (and I have so many dancing around my brain. Zucchini! Plum chutney! And a Canning 101 post about pickle texture!).

However, lots of you have been getting in touch wanting to know who won the MightyNest giveaway I posted last week. I’ve consulted Random.org and the winner is commenter #659. That’s Amanda F. who wrote, “We are trying to get rid of plastics in the kitchen. Those silicone popsicle molds look so much easier to remove than the plastic ones we currently have.”

Thanks to all of you who took the time to enter the giveaway! And you know, I think Amanda F. is right, those silicone popsicle molds look pretty darn awesome.

Upcoming Events: Chicago!

mussels and clams

Though it’s hard to believe, I’m actually coming to the end of my book tour summer. I’ll still doing classes and hope to do a bit of travel down south come January or February, but the huge promotional push I’ve been tangled up in since May 22 is drawing to a close.

I’m wrapping things up with a four days of events in the Chicago area and I can’t think of a finer way to conclude. If you call that area of the country home, I do hope you’ll come out and say hi this weekend (there are still seats available in Sunday’s class. Sign up and make jam with me!).

Saturday, August 25:

  • 9:30 – 11 am, canning demo and book signing at the Batavia Farmers’ Market. This event is free!
  • 12:30 – 2:30 pm, book signing at Morton Arboretum in Lisle. The event is included in the price of admission to the arboretum.
  • 5 pm, Jennifer Downing of Nourish Cooking is hosting an informal reception for me at the Yellow House. It’s your chance to get a book signed and ask me canning questions, all while nibbling tasty bits and having a cocktail or two. This event costs $30 if you want to include a copy of the book, or $10 for the reception only. Click here to sign up.

Sunday, August 26:

  • 9:30 – 11 am, canning class at Green Home Experts in Oak Park. The class costs $40 and includes a small jar of the jam we made in the class. Click here to sign up.
  • 11 am – 2 pm, book signing at Green Home Experts. While there will be books for sale on site, copies may be limited, call ahead to reserve yours.
  • 3 – 5 pm, I’ll be participating in the Chicago Food Swap (also being hosted by Green Home Experts). I’m planning on squirreling away some granola in my luggage to swap. The swap is currently sold out, but you can click here to get on the waiting list.
Monday, August 27 (events coordinated by the Lake Forest Book Store)

Credit for the coordination this Chicago trip goes to Emily Paster from West of the Loop, Jennifer Downing from Nourish Cooking and Naomi McEneely from the Lake Forest Book Store. They plotted, planned and strategized in order to make it reality. All three of them have my unending gratitude and appreciation. 

Photo note: I realize that the image at the top of this post has nothing to do with canning or this trip to Chicago. I took the day off yesterday and spent a lovely eight hours at the Jersey shore with a couple cousins that I don’t see nearly enough. We capped off the day by cooking clams and mussels together on an outdoor propane burner. It was joyous and every time I look at that photo, I feel happy and so wanted to share a little bit of that.

Weck Jar FAQ and MightyNest Giveaway

plum jam

It used to be that Weck jars were precious things, hard to come by outside of Germany. Then people started discovering how pretty and useful they are. Suddenly, stores from Crate & Barrel to Williams-Sonoma and beyond began stocking them.

No explanation is needed when it comes to storing dry goods in Weck jars, but when it comes to the actual act of canning in them, newcomers sometimes need a little help. A couple years ago, I wrote a step-by-step guide to using Weck jars, and while I have no intention of reinventing that particular wheel today, I do want to pluck out a few of the most commonly asked questions about canning in Weck jars and highlight them here so that they’re easy to access.

mixed plums

How do you tell if Weck jars are sealed? You can tell that Weck jars are sealed because the little tab on the rubber seal will point downwards. You can also test your seal in much the same way that you do with Ball jars. Once the jars are cool, remove the clips and grasp the lid of the jar. Lift off the counter an inch or two. If the seal holds fast, you’re golden. If it starts to lose its seal or breaks the suction entirely, that’s a jar that needs to be refrigerated.

Can you reuse the rubber seal? In all printed materials available in the US, they don’t recommend that you use the rubber seal for Weck jars more than once. However, I’ve been told the instructions printed in other countries tell you that it is reusable until it is stretched out or begins to lose its elasticity. Because I don’t like to take chances, I replace the rubber seal with each use.

Can you pressure can in Weck jars? I have not tried it personally, but I was told that it can be done, provided you add a third clip to the lid, in order to help prevent siphoning during processing.

Is it possible to buy replacement clips? It is! You can actually easily buy replacement clips, rubber rings and even lids for Weck jars. MightyNest, sponsor of today’s giveaway sells all the replacement parts in their canning section.

multi-colored plum jam

Because Weck jars are quite a bit more expensive than traditional mason jars, I tend to save them for my favorite preserves. These are the recipes that I like so much that I tend to either keep them all for myself or share them with only those people who are truly deserving.

Plum jam is one of my most beloved preserves, because its flavor reminds me of the rummy jam my mom used to make with the fruit from our backyard trees, in Southern California, when I was very young.

For this jam, I combined 5 cups of chopped plums (a mixture of yellow and red) with 2 1/2 cups of sugar. Once the juices started to run, I cooked the fruit and sugar over high heat until the fruit broke down and the syrup thickened enough to hang off the spatula in little pink windows. A squeeze of lemon juice went in at the end for balance. Processed for ten minutes in an array of Weck jars, this is one preserve I’ll be rationing this winter, to ensure it lasts until plum season returns.

Photos from a Tomato Canning Workshop

tomato canning workshop

The bulk of the canning classes I teach are demonstration style. This is in part because I’ve found that new canners feel more comfortable starting out by watching and learning.  It also doesn’t help that good, hands on teach space is hard to come by in the Philadelphia area.

prepping jars

Thing is, I love it when I have the opportunity to lead a hands on workshop. I only get to do one or two of those a summer, but I have so much fun when it happens. Today was a workshop day.

blanching and filling

Blooming Glen Farm hosted today’s workshop and provided 100 pounds of gorgeous red tomatoes for the canning. We blanched, peeled, acidified, packed and processed our way through every one of those tomatoes, which resulted in 52 quarts of peeled tomatoes packed in water.

full jars

 Speaking of tomatoes, I heard a couple of days ago that Lancaster Farm Fresh has a ton of organic tomatoes to move this season. They’re selling them in 25 pound boxes for just $25 a box. They have pick up locations in Pennsylvania, New York, Maryland and Washington, D.C., so this isn’t one just for my Philly-based folks. You can place an order by through this form or by calling 717-656-3533.

canning station

Last thing! We’ve got a winner in the Jars to Go Lunch Tote giveaway. Random.org has selected #164, which is Debra Meadow. Here’s how she uses her jars at lunch time, “Leftovers with a dollop of homemade sauerkraut and a jar of homemade beet kvass or kombucha. In a smaller jar I take crispy almonds and a coconut butter square for a snack.” Sounds delicious, Debra!

For those of you who didn’t win, but are still interested in getting one of these lunch totes, please know that the A Tiny Forest shop owner Kim is just one person with a sewing machine. She’s a little backed up thanks to all of you who want to buy her clever product, so please be kind and patient. I promise, your bag will be worth the wait. And, if you’re good with a sewing machine, she also sells the pattern, if you want to take a stab at making one yourself.

Canning 101: Learning to be Flexible

empty jam pot

I’ve made a lot of jam in my canning career. Between the years I logged as a kid helping my mom and all the many batches I’ve made as an adult, I’ve stirred and canned enough sweet preserves to fill a generously sized kiddie pool.

One thing I’ve learned in those hours over a canning kettle is that jam making is a lot like life. It’s not always going to be perfect, but you can almost always turn it into something useful and good.

When I teach jam making classes, one point I always emphasize is that you have two choices when you make a sweet preserve and it doesn’t turn out as you intended. You can either stress about it and try to redo it (and even then, you still might not be able to exactly hit your texture target), or you can change your expectations and move on.

I belong firmly to the school of changed expectations. Some days, I have a hell of a time getting my jam to set. As someone who prefers a softer set to start out with, this means that those underset jars are essentially sauce or syrup. So I call them just that. Instead of apologizing for my underset jam, I call these products sauce, or syrup or yogurt topping. I use them to glaze meat and tofu and I whisk them into vinaigrettes.

I’ve also made jams in the past that, once cool, set up into unforgiving blocks of rubbery fruit. They are so firm that they can be convinced to slide out of the jar in a single cylinder. Even in that case, it is still salvageable. You can serve little slices of that overset jam with a plate of cheese and charcuterie and call it a fruit paste (like membrillo). Or, you can cut it into cubes, roll it in granulated sugar and call it pâte de fruit.

These variations in set happen to the best of us and they can happen even with the most reliable recipes. I find that while past experience does inform every jam making session, you have to approach each batch individually.

Some years, fruit contains more water and less sugar. Other years, the opposite is true. On humid days, when a thunder storm is rolling in, the amount of moisture in the air can make it impossible to cook enough water out of the fruit to achieve a good set. The width of your pot can also impact your finished product, as can the power of your stove.

Depending on how the batch you’re making at the moment is behaving, you can adjust heat, cooking time and the quantity of additional pectin in an attempt to compensate. But  from year to year, there will always be a natural variation in set, length of cooking and even yield.

My very best advice is to try to learn to adapt, be flexible and exhibit some kindness to yourself, your preserves and the recipe writers who live in the same changeable world that you do.

Sustainable Eat’s August Urban Farm Handbook Challenge – Food Preservation Edition

The Urban Farm Handbook

Back in February, Annette from Sustainable Eats got in touch, asking me if I’d participate in her Urban Farm Handbook challenge in August. I said yes and now, a head-spinningly fast six months later, it’s my turn to issue a Food Preservation challenge.

So here’s what I’d like you UFH challenge folks (and anyone else who wants to play along) to try. Invent your own small batch jam recipe. I know it sounds counter-intuitive to ask people who are doing an urban farm challenge to think small during the height of canning season, but once you can piece together a small recipe, it will open up your brain and help you think creatively (though still safely) about your food preservation.

I realize that this sounds impossibly scary for some of you, particularly since we regularly hear from a number of sources that creating our own canning recipes is a big, fat no-no. However, here’s the thing. When you start with high acid fruits (and that’s the vast majority of them), and you add just a sweetener (sugar, honey or maple syrup all have the right chemical make-up to work well in this context) and you limit your flavor boosters to just a pinch of herb or spice, it’s really hard to create an unsafe product (though make sure to read through to the end of this post for the list of fruits that need more aggressive acidification).

lemon verbena

Start with a pound or so of fruit. Chop or mash it and measure how much you have. Add half as much sugar or maple syrup, or just a third of the volume of honey (it’s sweeter than the other two). Stir to combine and cook over fairly high heat in a stainless steel frying pan, stirring all the time. A low, wide pan will have the jam cooking down in ten minutes or less.

Add a splash of lemon juice if the sweetness needs balancing. A pinch of cinnamon is good if you want warmth. Star anise is tasty, as is a bit of vanilla bean, a few lemon verbena leaves or even a little freshly ground black pepper.

checking doneness

When you can draw a line through the cooking jam with your spatula and it holds it for a moment or two, it is done. Scrape the jam into small jars. They can be processed in a boiling water bath canner or just refrigerated.

Note: There are a few fruits that need to be acidified like tomatoes to ensure their safety. These are asian pears, white peaches and nectarines, figs, melons and tropical fruit. For every two cups of fruit pulp, add one tablespoon bottled lemon juice.

There are prizes for participating in the challenge. At the end of the month, Annette will publish a post in which everyone who participated can link up and then have a chance to win. Here’s what you could get:

Now, start canning!

Giveaway: Jars To Go Lunch Tote

ticking lunch bag

During my tenure as a full-time office employee, I packed my breakfast and lunch up in canning jars on a near-daily basis. I drank iced coffee out of a pint and a half jar, spooned yogurt out of a wide mouth pint and toted servings of soup around in whatever mason jar would do the job.

The one issue I always had with this food in glass habit was that the jars were prone to clanking in my lunch bag. Many times, I wished for a bag that kept them padded and contained.

mason jar lunch tote

Recently (and without knowing about my desire for such a product), the owner of the Etsy shop called A Tiny Forest got in touch. Kim wanted to know if I’d be interested in checking out her design. It was a handmade cloth lunch bag, fitted with padded sleeves that were intended to keep a pair of canning jars firmly in place. Of course I said yes.

When it arrived, I did my fair share of cooing and squealing over this sweet little bag (each one comes with a coordinating cloth napkin, a touch that makes me love it all the more). I even packed myself a little picnic as an excuse to use it. It does an excellent job of keeping the jars secure while still being roomy (and sturdy) enough to hold a piece of fruit and a big container of salad (or whatever other item you feel moved to add).

lunch tote

The bags come in a number of fabric choices and each one is delightful. With September just around the corner, treating oneself to a new lunch bag seems like the right choice (I don’t know about there rest of you, but I’ve never lost the desire for new pens, notebooks and back packs come Fall).

If a new lunch tote isn’t in the budget right now, you may also be in luck. Because Kim is lovely, she’s letting me give one of her sturdy bags away here on the blog. The winner even gets to choose the fabric, so if the classic blue striped number you see above doesn’t float your boat, there are many others to choose from. Here’s what to do to enter.

  1. Leave a comment on this post and tell me what your favorite home-packed lunch is.
  2. Comments will close at 11:59 pm east coast time on Friday, August 17. Winner will be chosen at random and will be posted to the blog on Saturday, August 18, 2012.
  3. Giveaway is open to US residents.
  4. One comment per person, please. Entries must be left via the comment form on the blog, I cannot accept submissions via email.
Disclosure: A Tiny Forest sent me a one of their lunch totes for trial and review and are providing an additional bag for giveaway purposes. My opinions, as always, remain entirely my own.

Tips for Tomato Canning Season

heirloom seconds

There’s been a rapid up-tick in questions about tomato preservation in the last week, so I thought I’d take a few minutes to gather all my tomato-centric posts in one place. Before you shoot me an email with a tomato query, take a look through these posts because your answer may be there.

Canning Whole Peeled Tomatoes – A basic tutorial that will walk you through the steps of canning whole tomatoes packed in their own juices. This is my preferred method for canning tomatoes for use throughout the year.

Tomato Canning 101 – If you’re dealing with floating tomatoes, a separated product or loss of liquid during processing, read this post in order to set your worries to rest.

Did your Sungolds, grape tomatoes and cherries do really well this year? Check out this post which details five ways you can preserve small tomatoes. On the flipside, if your bigger tomatoes are doing well, here are five ways to put them up.

Last summer, I made tomato paste for the first time. I wasn’t too keen on when I first did it, but I must confess, it’s been incredibly useful throughout this year. So much so, that I’m thinking of biting the bullet and doing it again (if I’m able to get a really good deal on tomatoes in the next few weeks).

Finally, no tomato post is complete without mention of my two favorite tomato jams. The classic and the one featuring yellow tomatoes and basil. Both are delicious.

In other news, the winner of the Mountain Rose Herbs giveaway is commenter #717, Elizabeth Dalton. Thanks to all who entered!
