What Is a Caper and How to Use Them in Recipes

March 2024 · 10 minute read

You might think capers are a fancy ingredient reserved for chefs in expensive restaurants. Or perhaps you’ve seen them on the grocery store shelf but were never quite sure what to do with them. Actually, capers are super-easy to use, and they’re perfect for adding a briny pop to all sorts of dishes — that’s why we love them in the First for Women test kitchen. Read on to find out what is a caper, then get eight recipes that are sure to become regulars on your dinner table. We promise: Once you learn more about these versatile flavor bombs, you’ll always want to have a jar of capers on hand.

What is a caper?

Bright, tangy, and infused with floral notes, capers are the small, unripe buds of the caper bush (Capparis spinosa), a plant grown in Italy, Spain, France, Morocco and other parts of the world. Ranging from the size of a petite green pea to a small olive, capers are generally associated with Mediterranean cuisine.

You can find them in the condiment aisle of your local grocery store, either jarred in brine or salt-packed. I like to stir them into sauces, stews, fish dishes and pasta, or I sometimes chop them up to add into salad dressings and marinades. You can also toss them into meatballs, sprinkle them over pizza or stir them into sautéed veggies. The possibilities really are endless!

What’s the difference between brined and salt-cured capers?

Much like olives, capers cannot be eaten straight from the bush or tree. They must be cured to enhance their flavor and texture. The two most common methods of preserving capers are brining and packing in salt. Brined capers are submerged in salt water or a vinegar mixture with preserves, while salt-packed capers are encrusted in sea salt. 

Brined capers, with their sharp edge and bold flavor, are super-convenient. All you need to do is drain the liquid and they’re ready to toss into your dish. Salt-packed capers retain a better texture, but they’re not as pungent and they take just a bit more time to prep. Simply rinse away the excess salt, soak them in cold water for about 10 minutes, then drain and pat dry.

What to do with liquid from the caper jar

When draining capers, don’t just toss the tangy liquid down the drain. Try adding a tablespoon or two of the salty brine to enhance dressing and marinades. I often stir a splash of caper brine into dips, sandwich spreads, pickling liquids and even drinks like Bloody Marys.

How to store capers

Once opened, a jar of brined capers can be stored in the fridge for up to six months. Just be sure the capers are completely submerged in the liquid. For salt-packed capers, store them, covered, in a cool dry place for up to a month.

What are caperberries?

While regular capers are picked when they are still young buds, caperberries develop after the flower has bloomed. They are about the size of an olive and are picked and pickled with the stem still attached. Generally, they are not as pungent as their smaller cousins, so caperberries are better as a garnish or stirred into a dish at the end of cooking. I like to serve caperberries on antipasto platters, charcuterie boards, salads or even to replace olives in a martini.
