Ingredients
  

  • 2 medium red onions thinly sliced
  • 1/2 cup balsamic vinegar
  • 1/4 cup water
  • 1 tablespoon sugar
  • 1 teaspoon salt
  • 1/2 teaspoon black peppercorns optional
  • 1 bay leaf optional

Instructions
 

  • Slice the onions: Cut the onions into thin slices and pack them tightly into a clean mason jar.
  • Prepare the brine: Heat balsamic vinegar, water, sugar, salt, and black peppercorns in a saucepan until it just begins to simmer.
  • Add aromatics (optional): Toss in the bay leaf for a subtle earthy touch.
  • Pour the brine: Carefully pour the hot mixture over the onions, ensuring they are fully submerged.
  • Cool and seal: Let the jar cool completely at room temperature before sealing and storing it in the refrigerator.
  • Marinate and serve: Let the onions marinate for at least 2 hours. Best flavor develops after 24 hours.
