Ingredients

  • 2 medium red onions thinly sliced

  • 1 cup vinegar
  • 2 to 3 tablespoons sugar
  • 1 teaspoon salt

Instructions

  • Peel the red onions and slice them thinly into slivers.
  • In a small pot, combine water and vinegar.
  • Bring to a boil over medium heat.
  • Add sugar and salt, stirring until fully dissolved.
  • Turn off the heat.

  • Mix so the onions are evenly coated and submerged.
  • Let cool completely in the brine.
  • Transfer to a clean jar.
  • Refrigerate and use as needed.

Notes

Slice onions evenly for consistent texture and better presentation.
Cane vinegar works well, but white vinegar gives a sharper taste.
Start with 2 tablespoons sugar, then adjust based on preference.
Let onions cool fully before bottling to avoid trapped heat.
Flavor improves after a few hours in the fridge.
