    No one in my family will eat regular dill pickles, but they sure do love these pickled onions! It's crazy how I've seen them use this condiment! Now, that's pickle love! ❤️

    How to make this recipe

    1. Add sliced red onions to a medium bowl. Pour boiling water over the onions to cover and let sit for 20 seconds. Drain onions and place in mason jar or bowl.
    2. Heat apple cider vinegar, lime juice, ⅛ cup sugar, chili flakes, and salt in a small saucepan over medium heat until sugar has dissolved, about 3 minutes.
    3. Pour vinegar mixture over onions. Allow to stand at room temperature, until fully cooled. 
    4. Seal and refrigerate for up to 2 weeks.

    TIPS & TRICKS

    • I used a mandoline to slice the red onions so they were uniform in size. If you don't have a mandoline, just make sure to slice the onions thinly (without slicing your finger!).
    • I used some red pepper flakes to spice up these red onions a bit, but if you're not a fan, just leave them out!
    • Store these pickled red onions in a mason jar. The mason jar has a really good rubber seal which makes them last longer in the fridge, at least two weeks!
