- 1 medium Red onion, sliced (or other vegetable such as carrots, cauliflower, or fennel)
- ½ cup Rice vinegar
- 6 tablespoons Sugar
- 2 teaspoons Kosher salt
- 1 teaspoon Black Peppercorns (optional)
Bring rice vinegar, sugar, salt, peppercorns (optional), and 1 cup of water to a boil. Pour over the onions and let sit for a day or so. These are best after a few days—and they should last up to a month.
