Detailed Directions and Instructions
Step 1: Blanch the Onions
Bring a pot of water to a boil. Add the thinly sliced red onion to the boiling water and blanch for about 30 seconds. This process will help soften the onions and enhance their color. After 30 seconds, drain the onions and transfer them to a heatproof jar.
Step 2: Prepare the Pickling Liquid
In a saucepan, combine ¾ cup of apple cider vinegar, ¾ cup of water, 1 tablespoon of granulated sugar, and 1½ teaspoons of kosher salt. If you are using any optional seasonings such as a clove of smashed garlic, whole black peppercorns, coriander seeds, fresh herbs, or citrus zest, add them to the mixture as well. Bring the mixture to a boil, stirring continuously to ensure the sugar and salt dissolve completely.
Step 3: Combine Onions and Pickling Liquid
Once the vinegar mixture reaches a boil, carefully pour it over the blanched onions in the heatproof jar. Ensure that the onions are fully submerged in the liquid to facilitate even pickling.
Step 4: Cool and Refrigerate
Allow the jar to cool to room temperature. After it has cooled, seal the jar tightly and place it in the refrigerator. The pickled onions will be ready to use after 30 minutes of pickling but will continue to develop more flavor the longer they are left to marinate.
