1. What Are Capers?

Capers are the unripened flower buds of the Capparis spinosa plant, commonly known as the caper bush. These bushes thrive in the Mediterranean region and other parts of the world with similar climates. The buds are harvested before they bloom, then they undergo a process of drying and pickling in salt, brine, or vinegar. This transforms them into the tangy, flavorful ingredient we know as capers. According to a study by the University of California, Davis, the pickling process not only preserves the capers but also enhances their unique flavor profile.

2. What Do Capers Taste Like?

Capers offer a distinctively savory flavor. They are known for being salty, briny, and having a bright, almost citrusy tang. Some describe them as having a slightly sour or puckery taste, especially the larger varieties. A small amount of capers can add a significant punch of umami to any dish.

3. Capers vs. Olives: What’s the Difference?

While capers and green olives share some similarities in their flavor profiles, there are key differences. Capers tend to be saltier and fresher, lacking the oiliness found in olives. Olives can have a more floral or buttery taste. Botanically, capers are flower buds, while olives are the fruit of the olive tree, specifically stone fruits. Both are commonly featured in Mediterranean cuisine, according to research from the Mediterranean Diet Roundtable Foundation.

4. What Are Caperberries?

Caperberries are the fruits that develop from the caper bush after the buds (capers) are not picked. They are larger than capers, roughly the size of a green olive, and have a crunchy texture with a milder flavor. Similar to capers, caperberries are typically pickled and sold in jars.

5. How to Cook with Capers

Capers are versatile and can be used in a variety of savory dishes. They work well in recipes where a boost of umami is desired. You can add capers directly to sauces or meat while cooking to infuse the entire dish with their flavor. Alternatively, they can be sprinkled over the finished dish to provide a salty, briny top note. The Culinary Institute of America recommends rinsing capers before use to remove excess salt.

To prepare capers, drain them from their jar and remove any excess brine. Larger capers may benefit from being minced or chopped before cooking to prevent their flavor from overpowering the dish.

6. What Are the Different Caper Varieties?

Capers come in various sizes, which reflect when the buds were harvested. Smaller capers are picked earlier in their development and are generally more expensive. According to “The Food Lover’s Companion,” the smaller the caper, the more intense its flavor.

Nonpareils: These are the smallest and most prized capers, known for their firm texture and delicate flavor.
Surfines and Capucines: These are slightly larger than nonpareils but still considered small and high-quality.
Capotes, Fines, and Grusas: These are the larger varieties of capers, which are softer, more flavorful, and can have a more pronounced acidic taste.

7. What Are Good Substitutes for Capers?

When looking for a caper substitute, it’s important to consider their unique flavor profile, which includes saltiness, brightness, and a juicy texture.

Some suitable substitutes include:

Green Olives: Many types of green olives can mimic the salty and savory notes of capers.
Preserved Lemons: These offer a similar bright and savory flavor.
Artichoke Hearts: Jarred artichoke hearts provide both complex flavor and juiciness.
Gherkins or Cornichons: Finely chopped, these pickles can offer a similar piquant and briny flavor.
Feta Cheese: Crumbled feta can add a salty and savory element.
Chopped Roasted Nuts: These can provide a textural element and some savory notes.
Fresh Herbs: Herbs like thyme can add aromatic complexity.
Flaky Sea Salt: A simple way to add a touch of saltiness as a finishing touch.

9. Are Capers Good for You?

Capers offer several nutritional benefits. They are rich in antioxidants, vitamins A and E, iron, and calcium. Additionally, they are low in cholesterol. However, pickled capers are high in sodium, which should be consumed in moderation. The Mayo Clinic recommends rinsing capers to reduce their sodium content before consumption.

10. How Do Capers Contribute to Mediterranean Cuisine?

Capers are integral to Mediterranean cuisine, providing a unique and versatile flavor component. Their briny, salty, and slightly tangy profile enhances a wide range of dishes, from salads and sauces to meat and seafood preparations. Their ability to add a burst of flavor without overpowering other ingredients makes them a staple in many Mediterranean kitchens. The Mediterranean diet, often praised for its health benefits, frequently incorporates capers in various recipes, highlighting their significance in this culinary tradition.

11. What Are Some Lesser-Known Uses for Capers?

12. What Are the Best Ways to Store Capers?

To maintain the quality and flavor of capers, proper storage is essential. Here are some tips for storing capers effectively:

Refrigerate After Opening: Once you open a jar of capers, always store them in the refrigerator. This helps to preserve their flavor and texture.
Keep Capers Submerged: Ensure that the capers are fully submerged in their brine or vinegar solution within the jar. This prevents them from drying out and maintains their moisture.
Use a Clean Utensil: When removing capers from the jar, use a clean utensil to avoid introducing bacteria or contaminants.
Check for Spoilage: Before using capers, check for any signs of spoilage, such as discoloration, off odors, or a slimy texture. If you notice any of these signs, discard the capers.
Consider Portioning: If you only use capers occasionally, consider dividing the jar into smaller portions and storing them in airtight containers or freezer bags. This helps to prevent the entire jar from spoiling if not used in a timely manner.

13. Can You Grow Your Own Capers?

Growing your own capers can be a rewarding experience, especially if you live in a suitable climate. Here are some key factors to consider if you’re interested in growing capers:

Climate: Caper bushes thrive in warm, dry climates with plenty of sunshine. They are typically grown in Mediterranean regions, but can also be cultivated in other areas with similar conditions.
Soil: Caper bushes prefer well-draining soil that is slightly alkaline. They can tolerate poor soil conditions, but optimal growth occurs in soil that is rich in nutrients.
Propagation: Capers can be propagated from seeds or cuttings. Seeds should be soaked in water before planting, while cuttings should be taken from mature plants.
Planting: Plant caper bushes in the spring, allowing ample space for them to grow. They typically reach a height of 3 to 5 feet and can spread several feet wide.
Care: Water caper bushes regularly, especially during dry periods. Fertilize them occasionally with a balanced fertilizer to promote healthy growth.
Harvesting: Capers are harvested in the early morning, before the buds open. They should be picked when they are firm and tightly closed.
Processing: After harvesting, capers need to be dried and pickled in salt, brine, or vinegar to develop their characteristic flavor.
