Ingredients

  • 3 large red onions, very thinly sliced
  • 1 cup tarragon red wine vinegar
  • 1 teaspoon sugar
  • 3 whole cloves
  • 4 black peppercorns, crushed

Instructions

  1. Place onions in a saucepan with the vinegar and enough cold water to cover.
  2. Add sugar, cloves, and crushed black peppercorns.
  3. Simmer over medium heat for 10 minutes or until the onions are tender.
  4. Refrigerate until ready to serve.

Tips & Substitutions

For a milder flavor, soak the sliced onions in cold water for 30 minutes before pickling. If you prefer a sweeter taste, you can increase the sugar to 1.5 teaspoons. Experiment with other vinegars, such as apple cider or white wine, for different flavor profiles. Adding a pinch of salt can also enhance the taste. These pickled onions are great in sandwiches or as a topping for salads like Apricot Citrus Salad.

Serving Suggestions

Serve pickled red onions as a tangy topping for tacos, burgers, or grilled meats. They also add a nice crunch to salads, especially Lime-Cabbage Salad. For a simple appetizer, pair them with cheese and crackers or serve alongside Spirit Balls for a delightful contrast. Their vibrant color and flavor make them a great addition to any dish.

Storage & Reheating

Store the pickled red onions in an airtight container in the refrigerator. They can last up to two weeks. If you plan to serve them later, allow them to marinate for at least a few hours for the best flavor. There's no need to reheat them; they are delicious served cold or at room temperature.

Frequently Asked Questions

Can I use other types of onions?

Yes, you can substitute red onions with shallots or yellow onions. However, red onions provide a sweeter flavor and vibrant color that enhances the dish. If you use yellow onions, consider adding a bit more sugar to balance their sharper taste.

How long do the pickled onions need to marinate?

For the best flavor, let the pickled onions marinate for at least 24 hours in the refrigerator. They will continue to develop flavor over time, and after a few days, the taste will become more pronounced. They can be enjoyed immediately but are truly best after a day.

Can I add other spices to the pickling mixture?

Absolutely! Feel free to experiment with additional spices such as cumin seeds, coriander seeds, or even a bay leaf for added depth of flavor. Just remember that each spice will impart its own unique taste, so start with small amounts and adjust according to your preference.
