Brine…
3 to 1 ratio of water to white vinegar. Add 1 tablespoon of kosher salt for every 1 cup of water used in brine.
Pack quart jars with sliced and scrubbed pickles, green beans, or brussel sprouts.
To each jar, add a slice of onion, smashed garlic clove, 1/2 t mustard seed, 1/2 t pepper corn, 1/2 t red pepper flakes, 1 bay leaf, and 1 head of dill or a generous sprig of dill frond. Fill to cover with brine and refrigerate. Ready in a week, lasts about a year.
Somehow we go through 3-4 gallons of these a year.
