Ingredients
- 2 large red onions, very thinly sliced (about 4 to 5 cups sliced)
- 2 cups (480 ml) apple cider vinegar, or distilled white vinegar
- 1 cup (240 ml) water
- 2 tablespoons granulated sugar
- 1 tablespoon kosher salt
- 1 teaspoon black peppercorns
- 4 cloves garlic, smashed
- ½ teaspoon red pepper flakes, optional, for a little heat
Instructions
- Thinly slice the red onions (a mandoline works great for paper-thin slices). Pack them tightly into a clean 2-quart glass jar (or divide them between two quart jars or four pint jars).
- In a small saucepan or microwave-safe bowl, combine the apple cider vinegar, water, granulated sugar, kosher salt, black peppercorns, smashed garlic cloves, and red pepper flakes (if using). Heat just until the sugar and salt have dissolved, about 1 to 2 minutes on the stovetop or 30 to 45 seconds in the microwave. Stir well. Do not boil.
- Pour the warm brine over the sliced onions, making sure they are completely covered. Use a spoon or chopstick to gently press the onions down so they stay submerged.
- Let the jar cool to room temperature, about 20 to 30 minutes. Seal the jar and refrigerate.
- The onions can be enjoyed after they have chilled for about 15 to 30 minutes, but they will have the best flavor after a few hours or overnight.
