1 large red onion – Thinly sliced.
1/2 cup (120ml) apple cider vinegar – Or white vinegar.
1/2 cup (120ml) water
1/4 cup (50g) granulated sugar
1 tablespoon salt – Non-iodized, such as kosher salt.
1/2 teaspoon black peppercorns – Lightly crushed.
1/2 teaspoon mustard seeds
1/2 teaspoon dried oregano – Or 1 teaspoon of fresh oregano.
1 garlic clove – Sliced (optional).
1/4 teaspoon red pepper flakes – For a bit of heat (optional).
Instructions
1. Prepare the Onions:
Slice Onions: Peel the red onion and cut it into thin, even slices. The thinner the slices, the quicker they will pickle.
2. Make the Brine:
Combine Ingredients: In a small saucepan, combine the apple cider vinegar, water, granulated sugar, and salt. Stir to dissolve the sugar and salt.
Add Spices: Add the black peppercorns, mustard seeds, dried oregano, garlic (if using), and red pepper flakes (if using) to the saucepan.
Heat Brine: Bring the mixture to a simmer over medium heat, stirring occasionally. Once the sugar and salt have dissolved, remove the brine from heat and let it cool slightly.
3. Pack the Jar:
Layer Onions: Place the thinly sliced onions in a clean glass jar or container. You can use a pint-sized jar or any container that’s appropriate for the amount of onions.
Add Brine: Pour the warm brine over the onions, making sure they are fully submerged. If the onions float, gently press them down with a spoon.
4. Cool and Store:
Cool: Let the jar cool to room temperature. Once cooled, seal the jar with a lid.
Refrigerate: Place the jar in the refrigerator. The pickled onions will be ready to eat in as little as 1 hour but will develop more flavor if allowed to sit for 24 hours.
Tips for Perfection
Slicing: Using a mandoline slicer can help achieve uniform, thin slices for quicker and more even pickling.
Flavors: Feel free to experiment with additional spices such as coriander seeds, bay leaves, or a small amount of fresh herbs to customize the flavor.
Storage: Pickled red onions will keep in the refrigerator for up to 2-3 weeks. They may become more flavorful over time.
