If you like capers, try mashing them with a fork and mixing with cream cheese for bagels. The same mixture is very good on ham sandwiches, or a veggie sandwich made with cucumbers, tomatoes and red onion. I also use it in stuffed burgers, and as a dip for veggies and crackers. If you like tartar sauce, make your own in minutes with some mayo, capers -- that's the secret ingredient -- and a dill pickle for a fraction of what a jar costs.
There are lots of delicious Italian, French and Spanish recipes that call for capers if you're looking for other ways to use them.
