Ingredients

  • 1 medium red onion
  • ½ cup white vinegar
  • 2 tablespoons white sugar (depending on preference go up to 1/4 cup sugar)
  • 6 black peppercorns
  • water to fill the jar

Instructions

    Cup of Yum
  1. Using the food processor with the fine slicing blade, or a mandolin, slice the red onion finely. If needed you can use a knife, just ensure you are slicing as thin as possible. 
  2. Add the onions to a jar (I typically use a 16 ounce Ball Jar). 
  3. Pour the white vinegar over the top of the onions. 
  4. Add the sugar and peppercorns. Then pour in water until the jar is filled. 
  5. Tighten the lid, and then shake the jar to combine the ingredients. 
  6. Place in the refrigerator and allow to sit for 1 hour before enjoying. These can be stored in the refrigerator for up to two weeks.

Notes

  • Onion Thickness: The thicker your slices of onion the longer they will need to sit for the vinegar to get all the way through the onion for flavoring. 
  • Storage: Store pickled onions in a sealed container in the refrigerator for up to 2 weeks. 
  • Canning: This is not a canning recipe. These do need to be stored in the refrigerator. Please follow a verified canning recipe if that is what you are looking for.
