Cook the Book: Pickled Red Onions

Cook the Book: Pickled Red Onions

I love pretty much anything pickled, cucumbers, tomatoes, mushrooms, watermelon rind, okra, even pickled eggs. I have to say that my favorite pickled item is the onion. Those little pickled pearl onions in my jar of cornichons disappear way before the last pickle and when I'm in the mood for a cocktail, a gin gibson is my drink of choice. Those beautiful pink pickled onions that are served with some tacos are my absolute favorite.

With all of this love for pickled onions it's surprising that I have never thought to put them on a burger. It was only while flipping through the pages of Bobby Flay's Burgers, Fries & Shakes that I realized pickled onions might just be the prefect burger accompaniment.

This is a quick pickling recipe, no need for boiling jars or long curing time. Simple mix the thinly sliced red onions with some acid, in this case vinegar and lime juice, some herbs, and some chiles for spice.
