Pickled Onions

My absolute favorite condiment, something I always keep in the fridge, is pickled onions. Maybe it’s the tangy, sweet taste, maybe it’s the crunchy texture, or maybe it’s that beautiful pink color, I don’t know, but these are a kitchen staple. Made with just a few simple ingredients like raw apple cider vinegar, sea salt, and freshly squeezed lemon juice, these onions marinate in the fridge and make even the simplest dishes something special.

How do I eat pickled onions? Honestly, there are endless ways. They brighten salads, add bright flavor to sandwiches and wraps, and make my breakfast plate a real dream. I’ve even been known to eat them right out of the jar with a fork (and so has my three year old!).
