Ingredients:
- 2 medium red onions (thinly sliced)
- 1 cup white vinegar (or apple cider vinegar)
- 1 cup water
- 1–2 tablespoons sugar (adjust to taste)
- 1 teaspoon salt
- Optional:
- 1 garlic clove (sliced)
- ½ teaspoon black peppercorns
- ½ teaspoon mustard seeds
Instructions:
- Prepare the onions
Peel and thinly slice the red onions into rings or half-moons. - Make the pickling liquid
In a small saucepan, combine vinegar, water, sugar, and salt. Heat gently until the sugar and salt dissolve (no need to boil). - Pack the jar
Place the sliced onions into a clean glass jar. Add optional ingredients like garlic or spices if desired. - Pour the liquid
Carefully pour the warm pickling liquid over the onions until they are fully submerged. - Cool and store
Let the jar cool to room temperature, then seal and refrigerate. - Ready to eat
The onions are ready in about 30–60 minutes, but taste even better after a few hours or overnight.
