PICKLED RED ONIONS

Pickled vegetables give unique and delicious flavors to any dishes that they’re paired with. The pickling process makes tangy onions that are savory and a little bit sour. This recipe uses white sugar as a sweetener to cut back on some of the sourness so that it’s just the right amount of tang.

TIPS FOR MAKING PICKLED RED ONIONS

  • Prep time: Use a sharp knife to slice each onion into thin slices. Then set the raw onions to the side while you prepare the pickling liquid. 
  • Pickling Marinade: Put 3 cups of water over medium heat and bring it to a boil, then turn off the heat. Add salt, sugar, and peppercorns to the hot water. (Be sure to use kosher salt and not table salt!) Stir until the salt and sugar have dissolved into the pickling brine. 
  • Combine: Add the pickles and onion, and stir until nicely combined. Leave the onion to sit in the liquid until it’s cooled. 
  • Pickle: Pour it into the mason jar and seal. Put the mason jar in the fridge for a minimum of 2 hours before you open and serve the Pickled Red Onions.

VARIATIONS ON PICKLED RED ONIONS

  • Additional seasonings: You can experiment with the flavors of the pickling mixture by adding in additional spices and fresh herbs. Try stirring a bit of allspice, paprika, rosemary, sage, thyme, coriander, or cumin with the pickling liquid. You could also add a hint of heat with some red pepper flakes. 
  • Spicy onions: If you want a stronger dose of heat than you can get from red pepper flakes, slice and deseed some jalapeno pepper to add to the recipe. Seal the pepper slices in the mason jar along with the rest of the ingredients. 
  • Citrus: To add some tangy, citrus flavor to the pickling brine stir in ¼ cup freshly-squeezed lime juice or add a few tablespoons of orange juice for some extra sweetness along with the tang. 
  • Asian flavors: If you want to serve Pickled Onions up with your favorite Asian cuisine, you can add some spices that go better with the Asian dish. A dash of ginger, star anise, turmeric, or cloves would all make amazing additions to the recipe. 
  • Garlic onions: For some delicious garlic goodness in the Pickled Red Onions, mince a clove of garlic or two and add them to the cooking liquid. The garlicky flavor will blend into the brine and get absorbed into the onion slices. 
  • Vinegar: You can try different kinds of vinegar brine. Apple cider vinegar, white vinegar, rice vinegar, or balsamic vinegar would all give their own unique taste to the recipe.
