Capers. These tiny, green, salty orbs often find themselves nestled beside smoked salmon, scattered atop pizzas, or swirling in Mediterranean sauces. But what exactly are they, and what does a caper actually taste like? Beyond their culinary ubiquity, lies a fascinating story of botany, brining, and bold flavor. Let’s delve into the world of capers and unlock their secrets.
What are Capers? Unveiling the Botanical Truth
Capers aren’t vegetables in the traditional sense. They are the unopened flower buds of the caper bush, scientifically known as Capparis spinosa. This perennial plant thrives in arid and semi-arid climates, particularly in the Mediterranean region, including Italy, Spain, Greece, and parts of North Africa.
The caper bush is a sprawling, thorny shrub with rounded leaves and beautiful, fragrant white or pinkish-white flowers. The buds are harvested by hand, a labor-intensive process that contributes to their relatively high cost. Harvesting typically takes place in the early morning hours, as the buds are at their most compact and flavorful before the sun fully opens them.
Once harvested, capers are inedible in their raw state. They undergo a crucial process of curing, either through brining in a salt solution or dry-salting, to develop their characteristic flavor and texture.
The Different Sizes and Their Significance
Capers are graded and sold according to their size, with the smallest being considered the most desirable and expensive. The grading system often varies by region, but some common size classifications include:
- Non-pareil: The smallest and most prized, typically measuring under 7mm.
- Surfines: Slightly larger than non-pareil, ranging from 7-8mm.
- Capucines: Between 8-9mm.
- Capotes: 9-11mm.
- Communes: The largest, exceeding 11mm.
Smaller capers, like non-pareil, tend to have a more delicate flavor and a firmer texture. Larger capers, while still flavorful, can be slightly softer and may have a more pronounced bitterness.
The Taste of Capers: A Symphony of Flavors
So, what does a caper taste like? It’s a complex flavor profile that is difficult to describe in a single word. The taste is definitely pungent, salty, and slightly sour or tangy. Fermentation during the curing process develops a distinctive aroma.
The brining or dry-salting process draws out moisture and concentrates the natural compounds within the bud, intensifying their flavor. This process also contributes to the caper’s characteristic salty taste. Some describe a subtle mustiness or a slightly sulfurous note, which adds to their complexity.
It’s important to note that the flavor of capers can vary depending on the size, the region where they were grown, and the curing method used. Some may be more intensely salty, while others might have a more pronounced sourness or a more herbaceous aroma.
Comparing Capers to Other Flavors
The flavor of capers is often compared to that of olives or pickled vegetables, but it has a distinct character. The combination of salt, acidity, and herbaceous notes sets it apart.
Some people find a similarity to green peppercorns, but capers lack the spicy heat of peppercorns. Their salty and briny flavor shares characteristics with sea beans, but with a more floral and less grassy quality.
Caper Berries: A Cousin with a Different Flavor
While capers are the unopened flower buds, caper berries are the mature fruit of the caper bush. These are larger than capers and have a more elongated shape, similar to a small olive.
Caper berries have a milder flavor than capers. While they still possess the characteristic salty and tangy notes, they are generally less intense and have a slightly sweet undertone. They also contain small seeds that add a subtle crunch.
Caper berries are often pickled or brined and are enjoyed as a snack or appetizer. They can be stuffed with cheese or used as a garnish for cocktails.
How Capers are Used in Cooking: A Culinary Chameleon
Capers are incredibly versatile in the kitchen. Their pungent flavor adds a delightful zing to a wide range of dishes. They are used in many different cuisines.
They are frequently added to Mediterranean dishes like pasta sauces, salads, and pizzas. Their briny flavor complements seafood, poultry, and vegetables beautifully.
Capers are a key ingredient in classic sauces like tartar sauce and piccata sauce. Piccata sauce, often served with chicken or veal, uses capers, lemon juice, butter, and white wine to create a flavorful, tangy sauce.
Capers can be added to salads for a burst of flavor. They pair well with tomatoes, cucumbers, onions, and other Mediterranean vegetables. They are also a delicious addition to potato salad or tuna salad.
Cooking with Capers: Tips and Techniques
- Rinse before using: Before adding capers to a dish, it’s generally recommended to rinse them under cold water to remove excess salt. This will help to control the overall saltiness of the dish. If the capers are particularly salty, you can soak them in water for a few minutes before rinsing.
- Add towards the end of cooking: Capers are best added towards the end of the cooking process, as prolonged heat can cause them to lose their flavor and become bitter.
- Fry for a crispy treat: For a unique twist, try frying capers in oil until they become crispy. Fried capers make a delicious garnish for salads, fish, or pasta dishes.
- Pair with complementary flavors: Capers pair well with acidic ingredients like lemon juice and vinegar, as well as rich ingredients like butter and olive oil. They also complement herbs like parsley, oregano, and thyme.
Where to Buy and How to Store Capers
Capers are widely available in most grocery stores. They are typically sold in small jars or cans, packed in brine or vinegar.
When choosing capers, look for those that are firm and plump, with a consistent green color. Avoid jars that appear cloudy or have signs of damage.
Once opened, capers should be stored in the refrigerator in their original brine or vinegar. They will typically last for several months if stored properly.
Exploring Different Types of Capers
While most capers are brined, some are dry-salted. Dry-salted capers tend to have a more intense flavor and a firmer texture. They also require rinsing before use to remove excess salt.
Capers preserved in vinegar are another option. These capers tend to be more acidic than those preserved in brine.
Nutritional Value of Capers
While capers are primarily used for their flavor, they also offer some nutritional benefits. They are a good source of antioxidants, which can help protect the body against cell damage.
Capers also contain quercetin, a flavonoid known for its anti-inflammatory properties. Additionally, they provide small amounts of vitamins and minerals, including vitamin K, calcium, and iron.
However, it’s important to consume capers in moderation due to their high sodium content.
Capers: A Tiny Bud with a Big Impact
Capers, despite their small size, pack a significant flavor punch. Their salty, tangy, and herbaceous taste adds a unique dimension to countless dishes. From classic Mediterranean cuisine to contemporary culinary creations, capers continue to delight and inspire cooks around the world. Whether you are a seasoned chef or a home cook, exploring the world of capers is a rewarding culinary adventure.
What is the predominant flavor profile of capers?
Capers offer a complex flavor profile that goes beyond simple saltiness. Their taste is often described as briny, salty, and slightly sour, with subtle herbal and floral notes. This piquant combination results from the brining or pickling process, which concentrates the natural compounds within the caper bud. The initial burst of saltiness is followed by a tangy acidity and a lingering vegetal undertone, making them a unique and versatile ingredient.
Beyond the basic salty-sour description, capers also possess a certain pungent quality, similar to mustard or horseradish, though much milder. This pungency contributes to their ability to cut through rich flavors in dishes and add a refreshing zip. The specific taste can vary slightly depending on the size and preparation method, with larger capers sometimes having a more pronounced bitterness.
How does the size of a caper affect its taste?
Generally, smaller capers, often called “nonpareilles,” tend to be more delicate in flavor and texture. They are prized for their firm, compact consistency and their more subtle briny and floral notes. Their smaller size also makes them easier to incorporate into dishes without overpowering other ingredients. These are typically the most expensive and highly regarded variety.
Larger capers, like “surfines” or “capotes,” have a more pronounced and intense flavor, often with a slightly more bitter edge. Their flesh is softer and more yielding, and they retain more moisture. While they may not be as visually appealing as the smaller varieties, their bolder taste makes them a good choice for dishes where you want the caper flavor to stand out more prominently.
What contributes to the salty taste of capers?
The salty taste of capers is primarily a result of the brining or pickling process they undergo during preservation. Fresh caper buds are naturally quite bitter and inedible. To make them palatable, they are typically soaked in a brine solution or packed in salt for a period of time. This process draws out the bitterness and replaces it with a concentrated salty flavor.
The specific salt concentration and duration of brining can influence the intensity of the saltiness. Capers packed in salt tend to be saltier than those brined in a liquid solution. Regardless of the method, the salt is crucial not only for flavor but also for preservation, helping to prevent spoilage and extend the shelf life of the capers.
Do capers have a distinct aroma?
Yes, capers possess a distinct aroma that complements their piquant flavor. The scent is a complex blend of salty, briny, and subtly herbal notes, with hints of mustard-like pungency. This unique aroma arises from the combination of volatile compounds released during the pickling process and the natural oils present in the caper bud.
The aroma of capers can also be influenced by the specific ingredients used in the brine or pickling solution. Some recipes may include herbs, spices, or vinegar, which can contribute additional aromatic layers. The overall aroma is generally described as refreshing and savory, adding to the overall sensory experience of consuming capers.
Are there any substitutes for capers in recipes?
While no single ingredient perfectly replicates the unique flavor of capers, there are several substitutes that can offer similar elements in a dish. Green olives, particularly those that are brined or packed in oil, can provide a salty and slightly briny note. Chopped cornichons or gherkins can also offer a similar sour and tangy flavor.
Another option is to use finely chopped green peppercorns, which have a slight peppery bite and can add a touch of pungency. For a saltier alternative, consider using a small amount of anchovy paste or chopped anchovies. Ultimately, the best substitute will depend on the specific recipe and the desired flavor profile.
How should capers be stored to maintain their flavor?
To maintain their flavor and quality, capers should be stored properly in an airtight container in a cool, dark place. If the capers are packed in salt, it’s important to ensure they remain fully submerged in the salt to prevent them from drying out. Properly stored salt-packed capers can last for several months.
For capers that are brined, refrigeration is recommended after opening the jar. Ensure the capers remain submerged in the brine to prevent them from drying out and losing their moisture. Brined capers typically have a shorter shelf life once opened compared to salt-packed capers, but they can still last for several weeks in the refrigerator.
What are some common culinary uses for capers?
Capers are a versatile ingredient used in a wide range of culinary applications. They are frequently added to Mediterranean dishes, such as pasta sauces, salads, and fish preparations, where their briny and tangy flavor complements the other ingredients. They are also a classic addition to sauces like tartar sauce and remoulade.
Beyond Mediterranean cuisine, capers are also used in various other dishes to add a burst of flavor and acidity. They are often included in egg dishes, such as scrambled eggs or omelets, and they can be sprinkled over roasted vegetables or used as a garnish for grilled meats. Their ability to cut through richness makes them a valuable addition to many savory dishes.
