These tangy, jewel-toned onions are the kind of condiment that makes everything on the plate look and taste more exciting. The brine comes together in minutes on the stovetop — apple cider vinegar, honey, and a warm trio of turmeric, ginger, and black pepper — then gets poured straight over thinly sliced red onion so the magic can start immediately. Every single ingredient here is naturally free of gluten, which means no label-scanning, no substitutions, and no stress about hidden additives sneaking into your condiment jar. Within 30 minutes you have something bright, lightly sweet, and gently spiced that works on tacos, grain bowls, grilled proteins, salads, or honestly just about anything that needs a little lift. The turmeric gives the brine a gorgeous golden hue that bleeds into the onions alongside that vivid pink, making this as visually striking as it is delicious. Keep a jar in the fridge and you'll find yourself reaching for it constantly — the flavor only gets better and more mellow as the days go on.

Pack the sliced red onion into a clean 16 oz glass jar, pressing gently so the slices fit snugly.
Combine the apple cider vinegar, water, honey, salt, turmeric, ginger, black pepper, and red pepper flakes (if using) in a small saucepan over medium heat, stirring until the honey and salt are fully dissolved, about 2–3 minutes. Do not boil.
