Ingredients

Pickling Ingredients

  • 1 large red onion, halved and thinly sliced
  • 1/2 cup red wine vinegar
  • 3 tablespoons sumac
  • 1 tablespoon kosher salt
  • 2 tablespoons finely chopped fresh parsley
  • 2 tablespoons finely chopped fresh mint

Instructions

  1. Combine the ingredients: In a medium bowl, combine the thinly sliced red onion with red wine vinegar, sumac, kosher salt, finely chopped fresh parsley, and finely chopped fresh mint to start the pickling process.
  2. Toss everything together: Using your hands, gently toss and massage the mixture to ensure the onion slices are evenly coated and the flavors start to meld.
  3. Let it sit: Cover the bowl and refrigerate the mixture for 30 minutes to 1 hour to allow the onions to soften slightly and absorb the tangy, herbaceous flavors.
  4. Serve: Use the pickled red onions immediately as a flavorful condiment or transfer them to a tightly sealed jar and store in the refrigerator for up to 1 week.

Notes

  • Use thin slices of onion to allow quick absorption of the marinade and optimal texture.
  • Sumac adds a lemony tang; if unavailable, a splash of lemon juice can be used as a substitute.
  • Fresh herbs like parsley and mint provide a fresh, bright flavor complementing the acidity.
  • Store in an airtight container to maintain freshness up to one week.
  • Perfect as a topping for tacos, salads, grilled meats, or sandwiches.
