Instructions
Thinly slice the red onion and place the slices in a heatproof bowl or jar.
In a small saucepan, combine the vinegar, water, sugar, salt, garlic, bay leaves, oregano, and any optional spices (cloves, cumin seeds, jalapeño or habanero).
Bring the mixture to a simmer over medium heat, stirring to dissolve the sugar and salt.
Pour the hot pickling brine over the sliced onions, ensuring they are fully submerged.
Let the mixture cool to room temperature. The onions will start to soften and turn a vibrant pink colour.
Once cooled, cover the bowl or jar and refrigerate for at least 1 hour before serving. For the best flavour, let the onions marinate for at least 4 hours or overnight.
Notes
Store the pickled onions in the refrigerator in an airtight container. They will keep for up to two weeks.
