Barbecue flavored cryo-pickled onions
Ingredients
1/3 cup vinegar2 tsp. barbecue rub (such as Vernon’s BBQ rib or beef rub)
½ medium-size yellow onion, thinly sliced
Preparation
• Combine the vinegar and barbecue rub in a bowl.
• Place the onions in a freezer bag and pour the seasoned vinegar over them.
• Seal the bag, removing as much air as possible. Shake the bag a little bit to make sure the onions are covered in vinegar.
