  • 1 red onion peeled and thinly sliced
  • 4 limes juiced
  • 1 Tablespoon cider vinegar
  • 1 teaspoon kosher salt
  • ½ teaspoon fresh ground pepper


  • In a glass bowl or jar, add all ingredients and toss to combine.
  • Refrigerate for at least 30 minutes before serving.
  • Taste again before serving and add salt if needed.



  • The onions will turn into a deep pink color the longer they're cured in the lime juice. I usually prepare this the night before I plan to serve them.
  • Can be stored in refrigerator, covered for up to 1 week.
