This pink pickled onion recipe will not only add a pleasing acidity to every dish you sprinkle them on, says Club Mexicana chef and founder Meriel Armitage, they also bring plenty of visual appeal to just about any dish: "Pink pickled onions are the jewel in our Club Mex crown! Any taco can look pretty with these pink beauties on top of it! They bring a disco vibe to every dish, and are well worth the effort for a taco party (even for one!). A jar of these can sit in your fridge for a few weeks — sprinkle them over tacos, roll into burritos, even add to leftover pizza. They not only look good, they taste banging too!"
