Tangy, jewel-bright, and ready to elevate just about anything on your plate, these pickled red onions are one of those condiments you'll want to keep stocked in the fridge at all times. A simple hot brine of apple cider vinegar, sugar, and kosher salt transforms raw onion slices into something almost magical โ soft, punchy, and that stunning shade of neon pink that makes every dish look like it came from a restaurant kitchen. Black peppercorns add a subtle warmth, and a pinch of red pepper flakes gives you just enough heat to keep things interesting. The whole process is refreshingly straightforward: pack the jar, pour the brine, and let time do the work. There's nothing hiding in here โ no nuts, no mystery additives, just clean pantry staples you can feel good about. Pile them onto tacos, grain bowls, burgers, sandwiches, or a simple cheese board and watch them disappear faster than you made them.
