Pickled onions are onions that have been preserved in a brine or vinegar solution, often with added sugar, salt, and spices.

Pickled onions come in a variety of flavors depending on the vinegar, spices, and sweeteners used in the recipe.

Ingredients:

2 large red onions (or yellow onions)
1 cup vinegar (white or apple cider vinegar)
1 cup water
1-2 tablespoons sugar (adjust to taste)
1 tablespoon salt
1/2 teaspoon black peppercorns
1/2 teaspoon mustard seeds (optional)
1 bay leaf (optional)
1 garlic clove (optional)

Instructions:

Prepare the Onions:
- Peel and slice the onions thinly. Use a mandolin or sharp knife to get even slices for uniform pickling.
Make the Pickling Liquid:
- In a saucepan, combine the vinegar, water, sugar, and salt. Add any optional spices like mustard seeds, black peppercorns, or a bay leaf.
- Bring the mixture to a boil over medium heat, stirring occasionally until the sugar and salt dissolve.
Pack the Onions into Jars:
- Place the sliced onions into a clean jar or jar(s). Make sure the onions are packed tightly but evenly.
Pour the Pickling Liquid:
- Once the pickling liquid is heated and the sugar and salt have dissolved, pour the hot liquid over the onions, covering them completely.
Let Cool:
- Allow the jar to cool at room temperature for about 15-30 minutes before sealing the jar with a lid.
Refrigerate:
- Refrigerate the jar for at least 1-2 hours before using. The onions will taste best after 24 hours, and their flavor will deepen the longer they sit in the brine.
Serve:
- Serve as a topping for tacos, burgers, sandwiches, or as a side dish. The pickled onions can be stored in the fridge for up to 2 weeks.

4. Tips for Making Perfect Pickled Onions

Use Fresh, Firm Onions: Choose firm onions for pickling to ensure they maintain their texture after being pickled.
Customize the Sweetness: Adjust the sugar amount based on how sweet you prefer your pickled onions. You can also experiment with different sweeteners like honey or maple syrup.
Spice It Up: Feel free to add extra spices such as cumin, coriander seeds, or red pepper flakes for added flavor.
Use Glass Jars: Always use clean, glass jars for pickling as they are non-reactive and help maintain the flavor.

5. How to Customize Your Pickled Onions

Vinegar Options: Experiment with different types of vinegar such as apple cider vinegar for a slightly fruity taste, or rice vinegar for a milder flavor.
Herbs and Spices: Add herbs such as thyme, rosemary, or dill to create a more complex flavor profile.
Add Garlic or Chiles: Garlic can add depth to the pickled onions, and adding chiles can bring some heat if you prefer a spicy version.

6. How to Store Pickled Onions

Pickled onions should be stored in an airtight jar or container in the refrigerator. They will stay fresh for up to 2 weeks, and the flavor will continue to develop the longer they sit in the brine.

7. Common Mistakes to Avoid

Not Using Enough Vinegar: Make sure the pickling liquid fully covers the onions to preserve them properly.
Overcrowding the Jar: Leave some room at the top of the jar to allow the pickling liquid to cover all the onions and avoid air pockets.
Skipping the Cooling Step: Allow the pickling liquid to cool slightly before sealing the jar to prevent the jar from cracking.
