Recipe: Quick and Easy Pickled Red Onions

Pickled Red Onion are life changing! Dramatic? Nah. Exaggerating? Nope. It’s just plain old love for the red onion. I can go on and list all the countless uses for the pickled red onion but I’ll keep it to a few.Add them to your salads, top your tuna/mayo sandwich or as a side with rich meats like pulled pork, or smoked meats.

I choose the red onion because of it’s relatively mild flavour along with it’s gorgeous purple/pink colour (so pretty). The vinegar provides the tang and cuts the sharp onion flavour, the sugar adds a nice balance to the salty vinegar brine, and the water tampers the pungent and lingering aftertaste of raw onions. Adding additional flavours is optional like garlic, chili clacked, or herbs. I prefer to keep my pickled onions simple but you do you. Happy Pickling Peeps!
