Peel and thinly slice the onion. For the best result, slice them as uniformly as possible.
In a small saucepan, combine the water, vinegar, sugar, and salt. Bring the mixture to a gentle boil, stirring until the sugar and salt have dissolved.
Place the sliced onions in a heatproof jar or bowl. Carefully pour the hot pickling liquid over the onions, ensuring they are fully submerged.
Let the onions cool completely to room temperature. This will take about 30-45 minutes. They will soften and become translucent.
Once cooled, if using, gently stir in the kefir for a creamy, tangy finish. If using dried herbs, sprinkle them in now.
Serve immediately or store in the refrigerator in an airtight container for up to 5 days. The flavor will deepen over time!
