What Are Capers? Everything You Need to Know About This Flavorful Mediterranean Ingredient

At first glance, capers may not look particularly impressive. They are small, round, and often found sitting quietly in a jar near olives, pickles, and other preserved foods.

But despite their tiny size, capers have a powerful ability to transform a dish.

A small spoonful can add:

  • a bright salty flavor,
  • a sharp tang,
  • a subtle bitterness,
  • a fresh Mediterranean character.

They are one of those ingredients that many people recognize by taste before they know exactly what they are.

You may have enjoyed capers in dishes such as chicken piccata, pasta sauces, salads, seafood recipes, and Mediterranean-style meals without realizing the unique story behind them.

So what exactly are capers, where do they come from, and why have they been valued for centuries?


What exactly are capers?

Capers are the unopened flower buds of the caper bush, a plant scientifically known as Capparis spinosa.

Before the flower blooms, the small buds are carefully harvested and preserved.

The buds are not usually eaten fresh because they have a strong, sharp flavor. Instead, they are traditionally preserved through:

  • salt curing,
  • brining,
  • vinegar preservation.

This process develops the flavor that makes capers famous.

The result is a small ingredient with a unique combination of salty, sour, and slightly spicy notes.


The caper plant: A Mediterranean survivor

The caper bush is well suited to warm, dry climates.

It grows naturally in regions around the Mediterranean, including areas of:

  • Italy,
  • Greece,
  • Spain,
  • Turkey,
  • North Africa,
  • parts of the Middle East.

The plant is surprisingly hardy.

It can grow in rocky, dry environments where many other plants struggle. Its ability to survive in harsh conditions has made it an important part of traditional agriculture in Mediterranean regions.

The bush produces beautiful flowers, but the small unopened buds are the part most commonly harvested for cooking.


How are capers harvested?

Capers require careful harvesting because the buds must be collected before they open into flowers.

Traditionally, harvesting is done by hand.

Workers carefully pick the small buds, often during the warmer months when the plant is actively producing them.

The size of the caper can affect its value.

Generally:

  • Smaller capers are often considered more delicate and desirable.
  • Larger capers usually have a stronger flavor and firmer texture.

After harvesting, the buds are sorted and preserved.


The different sizes of capers

Capers are often sold according to size.

Common categories include:

Nonpareils

These are the smallest capers.

They are often prized because they have:

  • a delicate texture,
  • balanced flavor,
  • elegant appearance.

They are popular in refined dishes and sauces.


Surfines

Slightly larger than nonpareils, surfines are still considered small and tender.


Capucines and larger varieties

These larger capers have a stronger texture and more noticeable presence in dishes.


Caper berries

Caper berries are different from regular capers.

Instead of the unopened flower bud, they are the fruit that develops after the flower has bloomed.

They are:

  • larger,
  • oval-shaped,
  • often served with stems attached.

Caper berries are commonly eaten as a snack, appetizer, or garnish.


What do capers taste like?

Capers have a distinctive flavor that is difficult to replace completely.

Their taste is often described as:

  • salty,
  • tangy,
  • slightly sour,
  • mildly bitter,
  • fresh and herbal.

The flavor comes from the preservation process.

Salt and vinegar bring out their sharp character, making them excellent for balancing rich foods.

For example:

A creamy sauce can feel heavy. Adding capers introduces acidity and brightness, making the dish taste more balanced.


Why are capers so popular in Mediterranean cooking?

Mediterranean cuisine often focuses on balance.

Many dishes combine:

  • fresh vegetables,
  • olive oil,
  • herbs,
  • seafood,
  • grains,
  • preserved ingredients.

Capers fit perfectly into this tradition because they add intensity without requiring large amounts.

Historically, preservation was also important.

Before modern refrigeration, methods like:

  • drying,
  • salting,
  • fermenting,
  • pickling

allowed people to keep flavorful ingredients available for longer periods.

Capers became a valuable way to add flavor throughout the year.


Popular dishes that use capers

Capers appear in many classic recipes.

Chicken piccata

One of the most famous uses of capers.

This dish typically combines:

  • chicken,
  • lemon,
  • butter,
  • sauce,
  • capers.

The capers add a sharp contrast to the rich sauce.


Pasta dishes

Capers are often added to pasta with ingredients such as:

  • tomatoes,
  • garlic,
  • olives,
  • anchovies,
  • olive oil.

They create a bold Mediterranean flavor.


Fish and seafood

Capers pair especially well with seafood.

They are often served with:

  • salmon,
  • tuna,
  • white fish,
  • shrimp.

Their salty acidity complements delicate seafood flavors.


Salads

A small amount of capers can add excitement to:

  • potato salads,
  • green salads,
  • grain salads.

Sauces and spreads

Capers are commonly used in:

  • tartar sauce,
  • remoulade,
  • Mediterranean spreads.

Are capers healthy?

Capers can be part of a healthy diet, especially when used as a flavor-enhancing ingredient.

They contain small amounts of:

  • antioxidants,
  • plant compounds,
  • minerals.

However, because they are usually preserved in salt or brine, they can also contain a significant amount of sodium.

People watching their salt intake may want to:

  • rinse capers before using them,
  • use smaller amounts,
  • balance them with fresh ingredients.

How to use capers in cooking

Capers are powerful, so a little often goes a long way.

Here are some simple ideas:

Add them to pasta

Mix capers with:

  • olive oil,
  • garlic,
  • tomatoes,
  • herbs.

Use them on roasted vegetables

A small sprinkle can brighten vegetables like:

  • potatoes,
  • asparagus,
  • zucchini.

Add them to sandwiches

Capers can add flavor to:

  • tuna sandwiches,
  • chicken sandwiches,
  • Mediterranean-style wraps.

Mix them into sauces

They work well in creamy or buttery sauces because their acidity creates balance.


Should you rinse capers before using them?

It depends on the recipe and your taste.

If you want a milder flavor:

  1. Drain the capers.
  2. Rinse them briefly under water.
  3. Add them to your dish.

If you enjoy a stronger salty flavor, you can use them directly from the jar.


How should capers be stored?

Unopened jars should be stored according to the label instructions.

After opening:

  • Keep them refrigerated.
  • Make sure they remain covered in their liquid.
  • Use a clean utensil when removing them.

Proper storage helps maintain their flavor and quality.


Can capers be substituted?

If you do not have capers, possible substitutes include:

  • chopped green olives,
  • finely chopped pickles,
  • a small amount of lemon juice,
  • pickled vegetables.

However, capers have a unique combination of salty and floral flavors, so substitutes will not be exactly the same.


Interesting facts about capers

They are flower buds, not seeds

Many people assume capers are seeds because of their small size, but they are actually unopened flower buds.


The flowers are beautiful

If allowed to bloom, the caper plant produces attractive flowers with delicate petals.


They have ancient culinary roots

Capers have been used for centuries in Mediterranean and Middle Eastern cooking.


They are a preserved food

Their traditional preservation methods helped make them valuable before modern food storage existed.


The difference between capers and caper berries

Although they come from the same plant, they are different.

Capers:

  • unopened flower buds,
  • small and round,
  • stronger salty flavor.

Caper berries:

  • mature fruit,
  • larger and oval-shaped,
  • often eaten whole.

Both are delicious, but they are used differently in cooking.
