  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon granulated sugar
  • 2 cloves garlic, minced
  • 1/2 cup dry white wine

• 1 tbsp kosher salt

For the onions:

• 1 bunch spring onions
• 1 tsp black peppercorns
• 1 tsp red pepper flakes

Instructions

1. Trim the root ends from 1 bunch spring onions and slice them into ¼-inch rounds.
2. Combine 1 cup white vinegar, 1 cup water, 2 tbsp sugar, and 1 tbsp kosher salt in a medium bowl.
3. Whisk the brine mixture vigorously for 30 seconds until the sugar and salt fully dissolve.
4. Add the sliced spring onions, 1 tsp black peppercorns, and 1 tsp red pepper flakes to the brine.
5. Press down on the onions with a spoon to ensure they’re completely submerged in the liquid.
6. Cover the bowl tightly with plastic wrap and refrigerate for exactly 1 hour.
7. Stir the pickled onions once after 30 minutes to distribute the spices evenly.
8. Drain the onions using a fine-mesh strainer, reserving the brine for another use if desired.
9. Transfer the pickled spring onions to an airtight container and refrigerate until ready to use.

Keep these quick pickled spring onions chilled for up to two weeks—their crisp texture holds beautifully. The sharp vinegar bite mellows into a sweet-tangy flavor that cuts through rich foods. Try them piled high on grilled burgers or stirred into grain bowls for an instant flavor upgrade.
