Let’s Cook
-
Prep the Onion
Thinly slice the red onion into ¼-inch moons. If using garlic, slice it in half. -
Make the Brine
In the jar or container you’ll store the onions in, combine sugar, salt, vinegar, and any optional flavorings. Stir until dissolved. -
Blanch the Onion
Boil 2–3 cups of water. Place the sliced onions in a sieve over the sink and slowly pour the boiling water over them to soften slightly. Let drain. -
Combine & Pickle
Add the onions to the vinegar mixture, stir gently, and make sure they’re submerged. -
Let Them Rest
Onions will be ready in about 30 minutes, but for best flavor, refrigerate for a few hours before serving. Store in the fridge for up to 2–3 weeks (best in the first week).
