Pickled Cipollini Onions

Onions, to be peeled

Peeled

Canned and sealed

Having made mustard and lime jelly during the past two weeks, it was time for more pickles, as I was running low. In addition to carrots, we decided to pickle cipollini onions again. I have friends who like the onions in cocktails or with a ploughman's lunch, but I seem to use most of mine on burgers. However you choose to use them, they improve greatly after a few weeks of storage time.

Pickled Cipollini Onions
Based on a recipe from the National Center for Home Food Preservation 

We ended up making two batches, some packed in standard wide-mouth pint jars and others layered, as above, in taller, thinner jars.

8 cups peeled cipollini onions (approximately 3 pounds purchased onions)
5½ cups white distilled vinegar
1 cup water
2 teaspoons canning salt
2 cups sugar
4 scant teaspoons mustard seed
2 scant teaspoons celery seed
Thyme (optional)

Yield: 3 pint and one 1/2 pint jars

Peel onions. I find that cipollini onions hold their shape well when peeled (see the photo above.)
Combine the vinegar, water, salt and sugar in a stockpot. Bring to a boil and continue to boil gently for 3 minutes. Add the peeled onions and bring the pot back to a boil. Reduce the heat and simmer until the onions are half-cooked (about 5 minutes).  
Meanwhile, place 1 scant teaspoon mustard seed and 1/2 scant teaspoon celery seed in the bottom of each clean, hot pint jar. I always add an optional thyme sprig, both because it looks nice and because I like the taste. If you are not a thyme fan you can omit it and/or experiment with a different flavor.
Ladle the hot onions into your jars, leaving 1-inch head space. Cover the onions with the hot pickling liquid, (a funnel helps with this) leaving ½-inch head space. Finger seal your jars and process in a boiling water canner for 10 minutes. 

If you have any brine leftover, as we did, I recommend using it for other pickles. We used our leftover brine for pickled carrots. For our usual pickled carrot recipe, see here. You could also use it for a refrigerator pickle of your choice, keeping in mind that the brine will have an onion flavor.

Carrots were part two of our project.
