Ingredient list for spicy pickled onions

how to make spicy pickled red onions

  • Prepare the Onions and Chili: Begin by thinly slicing 2 cups of red onions and ½ medium red chilli.
  • Combine the Ingredients: In a saucepan, combine apple cider vinegar, water, tablespoons of sugar, sea salt, and pepper. Stir the mixture over medium heat until the sugar and salt completely dissolve.
  • Bring to a Simmer: Once the mixture reaches a simmer, let it cook for a few minutes. This helps meld the flavors together and ensures the pickling solution is well-infused.
  • Layer the Onions and Chili: Layer the thinly sliced red onions and chili in a clean, sterilized jar.
  • Pour the Pickling Liquid: Carefully pour the simmered pickling liquid over the onions and chili, ensuring they are completely submerged. The heat of the liquid will start to soften the vegetables.
  • Cool and Refrigerate: Allow the mixture to cool to room temperature before sealing the jar and transferring it to the refrigerator. The longer the pickled onions sit, the more pronounced the flavors become. Aim for at least a few hours, if not overnight, for optimal taste.
  • Enjoy with Everything: These Spicy Pickled Onions are incredibly versatile. Add them to tacos, sandwiches, salads, or charcuterie boards for a burst of flavor. They also make a fantastic accompaniment to grilled meats or a topping for your favorite bowl of chili.

Tips and tricks

  • Thin Slicing: Ensure the red onions and chili are thinly sliced.
  • Swap ground pepper with 2 teaspoons of whole black peppercorns into the liquid. The peppercorns will impart a warm, earthy flavor that complements the onions' sharpness and the chili's heat.
  • Experiment with Chili Heat: Tailor the level of spiciness to your preference by adjusting the amount of red chili. For milder pickled onions, use less chili or remove the seeds. If you love the heat, keep the seeds and membrane for an extra kick.

  • Sterilize Your Jar: Before assembling your pickled onions, sterilize the jar to prevent unwanted bacteria. You can do this by washing it thoroughly and then placing it in a 250°F (120°C) oven for about 10 minutes or by running it through a hot dishwasher cycle.
  • Adjust Sugar to Taste: The sugar and salt quantities can be adjusted based on personal preference. If you prefer a sweeter taste, increase the sugar slightly.
  • Let Them Rest for Optimal Flavor: While it's tempting to dig into your pickled onions right away, allowing them to rest in the refrigerator for a few hours or, even better, overnight, enhances the flavors. This patience allows the pickling solution to penetrate the onions, resulting in a more robust taste.
  • Get Creative with Serving: Beyond traditional uses, get creative with how you serve these Spicy Pickled Onions. They make fantastic additions to cheese platters, grilled meats, or even as a topping for avocado toast. Let your culinary imagination run wild!

❓faqs

Are these pickled onions keto?

No, because they contain sugar. Remove the sugar to make these pickles keto friendly.

Why does the liquid look less than the onions?

This vinegar mixture is meant to cover the onions (not soak them)

Are these onions gluten-free?

Yes, they are.

Can I reuse the pickling liquid?

Don't discard the pickling liquid once you've finished the onions. Use it as a flavorful addition to salad dressings or marinades for an extra burst of tangy goodness.

Is it good to eat pickled onions?

Yes, pickled onions can be a tasty and healthy addition to your diet. While pickling involves preserving food in a solution of vinegar, salt, and sugar, the onions retain many of their nutrients. Onions are a good source of vitamins, minerals, and antioxidants; pickling can help preserve these benefits.

Pickled onions are generally low in calories. They can add flavor to your meals without significantly increasing your caloric intake, making them a great option for those looking to enhance their dishes without excess calories.

make-ahead and storage

MAKE-AHEAD CONVENIENCE: The beauty of this recipe lies in its make-ahead convenience. Once prepared, the pickled onions can be stored in the refrigerator, allowing the flavors to intensify over time. This makes them a perfect condiment to have on hand, ready to enhance your meals with a burst of spiciness whenever you need it.

STORAGE: Always store your pickled onions in the refrigerator. This preserves their crispness and ensures they stay safe to eat. Keep the jar tightly sealed to prevent the absorption of other odors from the fridge.
