Understanding Capers: What Are They, Exactly?

Capers are the unopened flower buds of the caper bush, scientifically known as Capparis spinosa. This shrub thrives in the rocky, dry landscapes of the Mediterranean region and parts of Asia and Australia. What we typically consume as capers are these flower buds that have been pickled or salt-cured. The plant itself is also important because it helps in preserving the soil.

The unique flavor of capers comes from glucocapparin, a glucosinolate compound. When the caper bud is crushed or processed, this compound breaks down, releasing an enzyme called myrosinase. This leads to the formation of compounds responsible for the distinctive pungent, mustard-like flavor we associate with capers. It’s this process of pickling or salting that develops and preserves this flavor profile.

The Truth About “Fresh” Capers

Technically, yes, you can find fresh caper buds. However, what’s crucial to understand is that fresh capers are not edible in their raw state. The glucocapparin content makes them incredibly bitter and unpalatable. Therefore, they must be processed – pickled in vinegar, brine, or salt-cured – to become the delicious capers we know and love.

So, while you might encounter “fresh” caper buds, keep in mind that they are essentially an ingredient waiting to be transformed. They’re not a ready-to-eat snack. You’ll need to put in the work to cure or pickle them yourself before they become edible and flavorful. The raw capers are very bitter and cannot be added raw to a dish.

Why You Don’t Typically Find “Fresh” Capers in Stores

There are several reasons why you’re unlikely to stumble upon truly fresh, unprocessed caper buds in your local supermarket:

Taste: As mentioned, their intense bitterness makes them unsuitable for direct consumption. The pickling or salting process is essential for developing the desirable flavor.
Shelf Life: Fresh caper buds have a very short shelf life. They deteriorate rapidly after being harvested, making them difficult to transport and store without processing.
Processing Requirement: The pickling or salting process is not just about flavor; it’s also about preservation. It inhibits microbial growth and extends the shelf life of the capers significantly.
Availability: Capers are primarily grown in Mediterranean regions. Transporting them fresh to other parts of the world would be logistically challenging and costly.
Consumer Preference: Most consumers are familiar with and expect to purchase capers that are already processed and ready to use. There’s simply not a large demand for raw caper buds.

Finding and Using Unprocessed Caper Buds

If you’re determined to experience the entire caper journey from bud to briny delight, there are a few ways you might acquire unprocessed caper buds:

Growing Your Own: If you live in a suitable climate, you can grow your own caper bush. This is the most reliable way to access fresh caper buds.
Specialty Growers/Farmers Markets: Occasionally, you might find specialty growers or farmers market vendors who offer unprocessed caper buds. It’s worth checking with local producers in Mediterranean-like climates.
Online Suppliers: Some online retailers may sell fresh caper buds during the harvest season. Make sure you understand the necessary processing steps before purchasing.

If you manage to obtain fresh caper buds, you’ll need to cure them yourself. The most common methods are:

Salt-Curing: Layer the caper buds with coarse salt in a jar or container. The salt draws out moisture and bitterness. Rinse the capers thoroughly after several days or weeks and then pack in oil or vinegar.
Pickling: Soak the caper buds in a vinegar-based brine. This method also helps to remove the bitterness and adds a tangy flavor.

Remember to research specific instructions and recipes for curing capers before you begin. It is important to follow the process carefully to ensure the capers are safe and palatable.

Pickled vs. Salt-Cured Capers: What’s the Difference?

The two main types of processed capers you’ll find in stores are pickled and salt-cured. The processing method significantly impacts their flavor and texture.

Pickled Capers: These capers are preserved in a vinegar-based brine. They tend to be softer in texture and have a pronounced vinegary tang. The flavor is often brighter and more acidic than salt-cured capers. They are typically rinsed before being added to recipes.
Salt-Cured Capers: These capers are preserved in coarse salt. The salt draws out moisture and concentrates their flavor. They are usually more intense and savory than pickled capers. Before using, they should be rinsed thoroughly to remove excess salt. Some cooks prefer to soak them in water for a short period to reduce the saltiness further.

The choice between pickled and salt-cured capers is a matter of personal preference and depends on the recipe. Salt-cured capers are often preferred for dishes where you want a more concentrated caper flavor, while pickled capers can add a bright acidity to sauces and salads.

Caper Sizes: From Nonpareilles to Grassa

Capers are graded and sold based on their size, which affects their price and, to some extent, their flavor and texture. The smallest capers are generally considered the most desirable and command the highest price.

Here’s a general overview of caper sizes, from smallest to largest:

Nonpareilles: These are the smallest capers, typically measuring less than 7mm in diameter. They are prized for their delicate flavor and firm texture.
Surfines: Slightly larger than nonpareilles, measuring between 7-8mm.
Capucines: Ranging from 8-9mm in diameter.
Fines: Between 9-11mm in diameter.
Grassa: The largest capers, measuring over 14mm in diameter. They tend to be softer and less flavorful than the smaller sizes.

When choosing capers, consider the recipe and your personal preference. Smaller capers, like nonpareilles, are often used in delicate sauces and salads, while larger capers might be better suited for dishes where you want a more pronounced caper flavor and texture.

Capers in the Kitchen: Culinary Uses and Tips

Capers are incredibly versatile and can add a burst of flavor to a wide range of dishes. Here are some popular culinary uses and tips:

Sauces: Capers are a key ingredient in classic sauces like puttanesca, piccata, and tartar sauce. Their briny flavor complements the other ingredients beautifully.
Salads: Capers add a salty and tangy kick to salads, especially those with Mediterranean or Italian flavors.
Fish and Seafood: Capers are a natural pairing for fish and seafood, adding a bright counterpoint to their delicate flavors.
Meat Dishes: Capers can be used to enhance the flavor of meat dishes, such as veal piccata or roasted chicken.
Antipasto: Capers are a popular addition to antipasto platters, adding a salty and briny element.
Pizza: Capers can be sprinkled on pizza to add a burst of flavor.
Vegetable Dishes: Capers can be used to add flavor to vegetable dishes, such as roasted vegetables or sautéed greens.

Tips for Using Capers:

Rinse Before Using: If using salt-cured capers, be sure to rinse them thoroughly to remove excess salt. Pickled capers may also benefit from a quick rinse to remove some of the vinegary tang.
Add Towards the End: Add capers towards the end of cooking to preserve their flavor and texture. Overcooking can make them bitter.
Experiment with Sizes: Try different sizes of capers to find the ones that you prefer.
Store Properly: Store capers in their brine or salt in a sealed container in the refrigerator.

Beyond the Flavor: Potential Health Benefits of Capers

While capers are primarily valued for their culinary properties, they also offer some potential health benefits:

Antioxidants: Capers are rich in antioxidants, which help protect the body against damage from free radicals.
Anti-inflammatory Properties: Some studies suggest that capers may have anti-inflammatory properties, which could help reduce the risk of chronic diseases.
Source of Vitamins and Minerals: Capers contain vitamins and minerals such as vitamin K, copper, and iron.

It’s important to note that these potential health benefits are based on limited research, and more studies are needed to confirm their effectiveness. However, including capers in a balanced diet can contribute to overall health and well-being.

The Final Verdict on Fresh Capers

While you can technically buy fresh, unprocessed caper buds, it’s important to understand that they are not edible in their raw state. They require curing or pickling to become the flavorful and enjoyable ingredient we know as capers. Most consumers are familiar with and expect to purchase processed capers, which are readily available in stores. If you’re adventurous and want to experience the entire caper journey, you can try growing your own or sourcing fresh caper buds from specialty growers. Just remember to follow proper curing or pickling techniques to ensure they are safe and palatable.

Are fresh capers readily available in most supermarkets?

Fresh capers are not commonly found in most mainstream supermarkets. The capers you typically see are pickled or salt-cured, a necessary process to make them palatable. The raw caper bud is naturally quite bitter and unappetizing due to the presence of glucosinolates, which need to be broken down through processing.

Because of this curing requirement, the supply chain for capers is almost exclusively focused on the preserved forms. Finding fresh capers would require specialized sourcing from farmers markets in regions where they are cultivated, or perhaps specialty grocers who import fresh produce directly. Their availability is limited even in regions where capers grow.

What do fresh capers taste like before being processed?

Prior to being pickled or salt-cured, fresh capers have a sharp, bitter, and almost acrid taste. This intense bitterness is due to the high concentration of glucosinolates, compounds also found in mustard and horseradish, but present in much greater quantities in raw capers. The unpalatable flavor necessitates preservation techniques.

Imagine an intensely bitter, somewhat grassy flavor with a slight peppery undertone. Most people find them extremely unpleasant in their raw state. This bitterness is precisely why the curing process is essential; it breaks down the glucosinolates, developing the more familiar and desirable briny, salty, and subtly floral flavor.

Why are capers typically preserved in salt or brine?

The process of preserving capers in salt or brine serves a dual purpose. Primarily, it removes the bitter compounds that make fresh capers unpalatable, creating the tangy flavor we associate with capers. This process also naturally preserves the capers, preventing them from spoiling and extending their shelf life significantly.

Salt or brine draws out moisture from the capers, creating an environment where spoilage-causing microorganisms cannot thrive. The salt concentration inhibits bacterial growth, allowing the capers to be stored for extended periods without refrigeration. This preservation method has been used for centuries in Mediterranean cuisine.

Can I preserve fresh capers at home if I can find them?

Yes, you can preserve fresh capers at home through either salt-curing or pickling in brine. Salt-curing involves layering the fresh capers with coarse sea salt and allowing them to sit for several days, replacing the salt as it becomes moistened. The salt draws out the bitterness and preserves the capers.

Pickling involves soaking the capers in a brine solution (typically a mixture of water, vinegar, and salt) for several weeks. Proper sanitation and adherence to recipe guidelines are essential for both methods to ensure the capers are safe to eat and properly preserved. There are many online resources and recipes that detail the specific steps involved in either method.

How should I store preserved capers (salted or pickled)?

Salted capers should be stored in a cool, dry place, ideally in their original salt. Make sure the salt completely covers them to prevent moisture absorption. If the salt becomes damp, replace it with fresh salt to maintain their preservation. They can last for a very long time when stored properly.

Pickled capers should be stored in their brine in the refrigerator after opening. Ensure that the capers are fully submerged in the brine to prevent them from drying out and to inhibit microbial growth. Properly stored pickled capers will typically remain good for several months after opening, but check for any signs of spoilage before consuming.

Are there different sizes of capers, and does size affect flavor?

Yes, capers come in various sizes, ranging from non-pareil (the smallest) to grusas (the largest). The size designation refers to the diameter of the caper bud. While all capers undergo a similar preservation process, the size can subtly affect both texture and flavor intensity.

Smaller capers, like non-pareils, tend to be firmer and have a more delicate flavor. Larger capers, like grusas, can be slightly softer in texture and have a more pronounced, bolder flavor. The choice of size often depends on personal preference and the specific dish being prepared. Generally, smaller capers are preferred for more delicate dishes, while larger ones are suitable for heartier preparations.

Can I substitute caperberries for capers, and what are the differences?

Caperberries are the fruit of the caper plant, while capers are the unopened flower buds. Both are typically preserved in brine or salt. While they share a similar flavor profile, they have distinct differences in texture and appearance and can be used as substitutes in some dishes, depending on the desired outcome.

Caperberries are larger than capers, resembling small olives. They have a milder, less intense flavor than capers and a softer, less firm texture. Caperberries are often served as an appetizer or garnish, while capers are more commonly used as an ingredient to add a salty, briny punch to various dishes. They can often be used interchangeably but will impart a different character to the final dish.
