Back when I made the pickled asparagus, I ended up having some brine leftover after I filled the jars. Not wanting to be wasteful, I poured what remained into a quart jar and shoved it towards the back of the fridge, to use another day. Over the weekend, I finally put it to good use.

I trimmed and quartered a pound of carrots, blanched them briefly (for no more than 15 seconds, as I didn’t want them to lose their crunch) and packed them into a wide mouth quart jar. Then I brought the brine to a quick boil and poured it in on top of the carrots. Several days later, they are piquant and a little bit spicy (I tucked a long red pepper into the jar along with the carrots).

I did not do a hot water process with these pickles and instead chose to keep them in the fridge. I did this for several reasons. The first is that it’s not advisable to use reboiled brine for shelf-safe pickles. Part of the reason that pickled vegetables are safe to eat after a hot water process is that the acidity of the vinegar keeps the nasty bacteria at bay. Regular canned vegetables, the ones that aren’t pickled, must be pressure canned to be safe. I knew that my leftover brine was plenty vinegary in terms of making my carrots taste amazing. However, I didn’t know whether the level of acidity was adequate in terms of keeping those carrots shelf-safe. So I decided to go the safe route, skip the water bath and opt for refrigeration as my means of preservation.

Additionally, sometimes I just want to make pickles, without hauling out a canning pot. Making a single jar with some leftover brine means that I can do just that. It took all of ten minutes to make those pickled carrots and now I have something delicious to go with soup, a sandwich, salad or just munched alone (and since the pickled asparagus I made a few weeks back is long gone) for the next week or so.

For those of you who don’t have some extra brine sitting around your fridge, here’s a quick formula for making a small batch of brine, so that you can make just one or two jars of pickles at a time.

Small-Batch Pickling Brine

1 cup filtered water
1 cup apple cider vinegar (make sure it’s commercial vinegar that is at least 5% acidity)
1 tablespoon pickling salt (or 1 1/2 tablespoons kosher salt)

A palmful (each) of at least a few of the following:

• crushed bay leaves
• peppercorns
• hot pepper flakes
• allspice berries
• coriander seeds
• whole cloves

Pour the water, vinegar, salt and spices into a small saucepan. As it comes to a boil, pack your veggies into a freshly washed jar (one pound of trimmed and quartered carrots fits nearly perfectly into a wide-mouth quart-sized jar). You can also tuck a slice of lemon, a hot pepper or a garlic clove into the jar as well. When the brine is boiling, pour it into the veggie-packed jar, leaving about 1/2 inch of headspace. Make sure to run a butter knife around inside the jar, to release any air bubbles trapped behind the vegetables (this isn’t as important in this case as it is when you’re doing a hot water bath, but it’s a good habit to get into anyway).

Gently screw a two-part canning lid on the jar (making sure to protect your hands with a towel or potholder) and let it sit until it’s cooled down. The lid may seal during the cooling process. However, this does not mean it’s safe to store it at room temperature indefinitely. Once the jar is fairly cool, it should still go in the fridge. Let them chill out in the brine for at least 2-3 days before you dig in.

I know it reads like a lot of steps to follow, but really, it takes no time. So go pickle something already.
