Instructions

Directions for quick pickled red onions:

  1. Combine the water and vinegar in a small saucepan and heat over medium heat.
  2. Add sugar and stir until dissolved.
  3. Remove from heat and cool.
  4. Use a sharp knife to slice the onions thinly and evenly. Use a mandoline if you have one and want to get them super thin and uniform.
  5. Place sliced onions in clean mason jar, leaving 1 inch at the top.
  6. Add peppercorns to the jars and pour the vinegar mixture into the jars.
  7. Add desired aromatics like ginger, garlic, dill, crushed red pepper flakes, etc.
  8. Place waxed paper or plastic wrap over top of jar and screw on the lid. The plastic wrap will keep the top from discoloring from the vinegar.
  9. Let the onions marinate in the refrigerator for at least one hour or up to two weeks.
  10. Enjoy!

Notes

Note- When dipping in to serve the pickled red onions, use a clean spoon to retrieve onions from jar to avoid cross contamination.

Some recipes call for Apple Cider Vinegar, and while you can use this in a pinch, I think it imparts too much sweetness to the onions and the sweetness eclipses their bright flavor. Other recipes call for rice vinegar, which works well for some dishes.
