In Mexico, pickled onions are to taco stands what pickle relish is to a hot dog cart in the U.S.—a condiment that taco-lovers can’t do without. Make it at home and save yourself the trip across the border.

Ingredients

　　1 red onion, thinly sliced

　　3/4 cup distilled white vinegar

　　6 tablespoons sugar

　　1/2 teaspoon crumbled dried oregano

　　1/2 teaspoon salt

　　Combine the onion, vinegar, sugar, oregano, salt, and 3/4 cup water in a large self-seal plastic bag. Shake the bag to combine the ingredients. Let the onion marinate for at least 24 hours and up to 4 days in the refrigerator.
