The caper, a culinary treasure often found nestled in Mediterranean cuisine, possesses a unique flavor profile that elevates countless dishes. But what exactly is a caper? Beyond its briny, salty tang, lies a fascinating story of botany, cultivation, and culinary application. This article will delve deep into the world of capers, exploring their origins, how they’re grown and processed, their distinctive taste, and their versatility in the kitchen.
The Caper Plant: More Than Meets the Eye
The caper, scientifically known as Capparis spinosa, is a perennial shrub native to the Mediterranean region and parts of Asia. This hardy plant thrives in arid climates and rocky terrains, often clinging to walls and cliffs. It’s characterized by its sprawling branches, round, fleshy leaves, and striking white flowers with prominent purple stamens.
Understanding the Caper: Bud vs. Berry
The part of the plant we know as the “caper” is actually the unopened flower bud. These buds are hand-picked before they bloom and then preserved, usually through pickling in vinegar, brining in salt, or drying. The size of the caper bud varies, with smaller buds generally considered to be of higher quality and commanding a higher price.
The caper bush also produces a fruit known as the caper berry. This fruit, larger than the bud, is also pickled and eaten, although it has a different flavor and texture. Caper berries are typically served whole, often with the stem still attached, and have a milder, less intense flavor than caper buds.
Cultivation and Harvesting
Caper cultivation is a labor-intensive process, relying heavily on manual harvesting. The plants thrive in sunny locations with well-drained soil. Harvesting takes place over several months, typically from late spring to late summer, as the buds mature at different rates.
The buds are picked early in the morning before the heat of the day causes them to open. Skilled workers carefully select the buds, ensuring they are of the desired size and firmness. This process requires patience and precision, contributing to the caper’s reputation as a relatively expensive ingredient.
Processing Capers: From Field to Table
Freshly harvested caper buds are inedible due to their bitter compounds. They require processing to develop their characteristic flavor and become palatable. The two main methods of preservation are brining and pickling.
Brining: The Traditional Method
Brining involves soaking the caper buds in a salt solution for several days or weeks. This process draws out moisture and bitter compounds, while also allowing the buds to ferment slightly. The brining process also contributes to the caper’s signature salty flavor.
After brining, the capers are typically rinsed and sorted by size. They are then packed in brine or salt for storage and sale. Salt-cured capers have a more intense flavor and require rinsing before use.
Pickling: A Tangy Alternative
Pickling involves soaking the caper buds in a vinegar solution. This method also draws out bitterness and preserves the buds, but it imparts a tangy, acidic flavor. Pickled capers are often combined with other ingredients, such as herbs and spices, to enhance their flavor.
Caper Sizes: A Matter of Preference
Capers are graded and sold according to size, with smaller sizes generally considered more desirable. The smallest capers, known as “nonpareilles,” are prized for their delicate flavor and firm texture. Larger capers, while less expensive, still offer a distinctive taste and are suitable for various culinary applications.
| Size | Diameter (mm) | Description |
|---|---|---|
| Nonpareilles | 7-9 | Smallest and most prized |
| Surfines | 9-11 | Slightly larger than nonpareilles |
| Capucines | 11-13 | Medium-sized capers |
| Capotes | 13-15 | Larger capers with a more pronounced flavor |
| Communes | 15+ | The largest and least expensive capers |
The Flavor Profile: A Briny Burst
Capers possess a unique and complex flavor that is both salty and tangy, with subtle floral and mustard-like notes. This distinctive taste comes from a combination of factors, including the plant’s natural compounds, the preservation method, and the size of the bud.
The brining or pickling process concentrates the flavors and creates a characteristic pungency. This intense flavor makes capers a powerful ingredient, capable of adding depth and complexity to a wide range of dishes.
The small, firm texture of the caper bud also contributes to its appeal. When bitten into, capers release a burst of flavor that awakens the palate.
Culinary Uses: Versatility in the Kitchen
Capers are a staple ingredient in Mediterranean cuisine, adding a burst of flavor to sauces, salads, and main dishes. Their versatility extends beyond Mediterranean fare, however, making them a welcome addition to various cuisines around the world.
Sauces and Dressings
Capers are commonly used in sauces, such as tartar sauce, remoulade, and puttanesca sauce. Their salty, tangy flavor complements the richness of these sauces and adds a welcome counterpoint to other ingredients. Capers can also be added to vinaigrettes and other dressings to create a more complex and flavorful dressing.
Salads and Appetizers
Capers are a popular addition to salads, adding a briny kick to green salads, potato salads, and pasta salads. They pair well with ingredients like tomatoes, olives, and feta cheese. Capers can also be used as a garnish for appetizers, such as smoked salmon or bruschetta.
Main Dishes
Capers are often used to enhance the flavor of main dishes, particularly those featuring fish, chicken, or veal. They can be added to pan sauces, stews, and casseroles. Chicken piccata, a classic Italian dish, features capers as a key ingredient.
Creative Culinary Applications
Beyond traditional uses, capers can be incorporated into a variety of creative dishes. They can be added to pizza toppings, stirred into scrambled eggs, or used as a garnish for cocktails. Their unique flavor profile makes them a versatile ingredient for adventurous cooks.
Health Benefits: More Than Just Flavor
Beyond their culinary appeal, capers offer several potential health benefits. They are a good source of vitamins and minerals, including vitamin K, copper, and rutin.
Rutin, a flavonoid found in capers, has antioxidant and anti-inflammatory properties. Studies have suggested that rutin may help protect against chronic diseases, such as heart disease and cancer.
Capers are also a low-calorie and low-fat food, making them a healthy addition to a balanced diet.
Buying and Storing Capers
When buying capers, look for those that are firm and uniformly sized. Avoid capers that appear shriveled or discolored. Brined capers should be submerged in brine, while pickled capers should be submerged in vinegar.
Capers should be stored in their original liquid in the refrigerator. Properly stored, capers can last for several months. Once opened, capers should be used within a few weeks for optimal flavor.
Caper Substitutes: When You’re in a Pinch
While capers offer a unique flavor, there are a few substitutes that can be used in a pinch.
- Green Olives: Chopped green olives can provide a similar salty and slightly briny flavor.
- Pickled Green Tomatoes: These offer a tangy and slightly sweet flavor.
- Nasturtium Seeds: These seeds have a peppery, caper-like flavor.
- Dill Pickles: Finely chopped dill pickles can add a tangy, salty element.
Keep in mind that these substitutes will not perfectly replicate the flavor of capers, but they can provide a similar taste profile in certain dishes.
Capers: A Culinary Essential
Capers, with their unique flavor, fascinating history, and versatile applications, are a culinary essential for any home cook. From adding a burst of flavor to sauces and salads to enhancing the taste of main dishes, capers offer a world of culinary possibilities.

What exactly is a caper and what part of the plant does it come from?
The caper that we enjoy in culinary dishes is the flower bud of the caper bush, scientifically known as Capparis spinosa. This perennial plant is native to the Mediterranean region and thrives in rocky or wall habitats. The flower buds are harvested before they bloom, as this is when they possess the most intense flavor.
These buds are then pickled in a brine or dried and salted. This curing process is essential to developing the characteristic tangy, salty, and slightly pungent flavor that capers are known for. Without this process, the buds would be quite bitter and unpalatable.
What does a caper taste like and how does its flavor profile contribute to dishes?
Capers boast a distinctive flavor profile that is primarily salty, tangy, and slightly pungent. The salty element comes from the brining or salting process used to preserve them, while the tanginess stems from the natural acids present in the plant. The subtle pungency adds a layer of complexity that enhances their overall taste.
This unique combination of flavors allows capers to act as a potent flavor enhancer in a variety of dishes. They contribute a briny zest that can cut through richness, balance sweetness, and add a bright, savory element. They are often used to add depth and complexity to sauces, salads, and meat dishes.
How are capers typically processed and preserved after harvesting?
After harvesting, capers undergo a crucial preservation process to transform their naturally bitter taste into the flavorful ingredient we know. The most common method involves pickling them in a brine solution, typically a mixture of water, salt, and vinegar. The salt draws out moisture from the buds and helps to inhibit microbial growth, thereby preserving them.
Another method involves drying and salting the capers. They are spread out and allowed to dry in the sun or in a dehydrator. Once dried, they are heavily salted, which further preserves them and intensifies their flavor. Regardless of the method, this curing process is vital for developing the capers’ signature taste and extending their shelf life.
Are there different sizes of capers and does size affect the flavor?
Yes, capers are categorized by size, ranging from the smallest, known as “nonpareil” (typically less than 7mm in diameter), to larger varieties like “surfines” and “capotes.” The size of the caper can subtly influence the flavor and texture. Smaller capers, like nonpareils, are prized for their delicate texture and more intense flavor, as they have a higher skin-to-pulp ratio.
Larger capers, on the other hand, have a slightly milder flavor and a more pronounced floral note. While the difference is subtle, experienced cooks often choose capers based on size depending on the desired impact on the dish. Smaller capers are generally preferred for dishes where a strong, concentrated burst of flavor is needed, while larger capers are better suited for dishes where a more subtle, textural element is desired.
What are some popular culinary uses for capers in Mediterranean cuisine and beyond?
Capers are a staple in Mediterranean cuisine, adding a burst of flavor to a wide range of dishes. They are commonly used in sauces like puttanesca and piccata, where their briny tang complements the other ingredients. Capers are also frequently added to salads, such as Niçoise salad, and used as a topping for grilled fish or chicken.
Beyond the Mediterranean, capers have found their way into various cuisines around the world. They are often incorporated into dips, spreads, and relishes. Their ability to cut through richness makes them a popular ingredient in dishes with creamy sauces or fatty meats. They provide a unique and versatile flavor element that can elevate many culinary creations.
Are there any nutritional benefits associated with consuming capers?
Capers offer several nutritional benefits, although they are typically consumed in small quantities. They are a source of antioxidants, particularly rutin and quercetin, which may help protect cells from damage caused by free radicals. These antioxidants are known for their potential anti-inflammatory and anti-cancer properties.
Furthermore, capers contain vitamins and minerals, including vitamin K, copper, and iron. While the amounts are relatively small per serving, they can contribute to overall nutrient intake. However, it’s important to note that capers are high in sodium due to the brining process, so moderation is key, especially for individuals with sodium-sensitive conditions.
Can capers be substituted with other ingredients in recipes?
While capers have a unique flavor, there are a few ingredients that can be used as substitutes, although none will perfectly replicate their distinct taste. Green olives, especially those that are brined, can provide a similar salty and briny flavor. Chopped green olives can be used in equal amounts as capers.
Another possible substitute is pickled gherkins or cornichons, which offer a similar tangy and acidic bite. However, they lack the saltiness of capers, so a pinch of salt may be necessary. Ultimately, the best substitute will depend on the specific dish and the desired flavor profile. Experimentation is key to finding the right alternative.
