Ingredients
  

  • 1 cup (240 ml) apple cider vinegar
  • 1 cup (240 ml) red wine vinegar
  • 2 tablespoons (30 g / 1.06 oz) granular erythritol, or more to taste
  • 1 teaspoon (6 g / 0.21 oz) sea salt
  • 2 medium red onions, thinly sliced
  • 6 cloves garlic, halved
  • 1 teaspoon (5 ml / 0.2 fl oz) dried oregano leaves
  • 1 pinch red pepper flakes
  • For a crunchier onion, slice them slightly thicker. For a softer texture that melds into dishes, slice them paper-thin using a mandoline.
  • Experiment with different spices like whole peppercorns, bay leaves, or mustard seeds for a unique flavor profile.
  • If you're not following a keto diet, you can substitute the erythritol with an equal amount of granulated sugar or a tablespoon of maple syrup.

Method
 

  1. Directions
  2. In a saucepan over medium heat, bring the apple cider vinegar, red wine vinegar, erythritol, and salt to a light boil, stirring until the erythritol and salt have dissolved.
  3. Place the sliced onions, halved garlic, oregano, and red pepper flakes into a 32-ounce / 1-liter mason jar. Carefully pour the hot vinegar mixture over the top, ensuring everything is fully submerged.
  4. Allow the jar to cool on the counter for at least 1 hour.
  5. Once completely cool, secure the lid and transfer to the refrigerator.
  6. While they can be enjoyed the next day, their flavor deepens and improves after a few days.
  7. Store in an airtight container in the refrigerator for up to one month.
  8. Don't discard the leftover pink brine! Use it as a base for vinaigrettes or to add a tangy kick to marinades.
