These pickled spring onions can play a number of roles. Dolloped on top of a burger, a basic cookout becomes quite gourmet. Need to bring an appetizer to a party? Toast baguette rounds, add a smear of creamy goat cheese and top with a bit of pickled onion. A bowl of baby arugula becomes a salad with a forkful of pickled onions and a drizzle of olive oil.

Ingredients

  • 1 bunch spring onions (approximately 1/2 pound once trimmed and cleaned)
  • 1/2 cup apple cider vinegar
  • 1/4 cup water
  • 3 tablespoons sugar
  • 1 teaspoon sea salt
  • 1 teaspoon mustard seeds
  • 1/2 teaspoon celery seed
  • 1/8 teaspoon red chili flakes

Directions

  1. Prepare a small boiling water bath canner and one pint jar.

  2. Wash and thinly slice trimmed spring onions into thin rounds. In a small pot, combine vinegar, water, sugar, salt, mustard seeds, celery salt and red chili flakes. Bring to a boil. Once brine is simmering, add onions. Stir to combine and cook until onions are heated through, 2 to 3 minutes.

  3. Remove pot from heat and funnel onions into prepared pint jar. Wipe rim, apply lid and ring, and process in a boiling water bath canner for 10 minutes. When time is up, remove jar from canner and let it cool. Check to ensure a good seal once jar is cool.

  4. Let pickles rest at least two days before using. Unopened, this pickle will keep for up to one year in a cool, dark place. Once opened, keep refrigerated and use within 2-3 weeks.
