Capers Growing Guide Part 6
Introduction
Capers, the small flower buds of the caper bush (Capparis spinosa), have long been cherished for their unique flavor and culinary versatility. Though often overlooked in discussions of gourmet ingredients, these little bursts of briny delight play a vital role in Mediterranean cuisine and beyond. This guide delves into the multifaceted aspects of growing capers, from their historical significance to practical considerations for cultivation, processing, and storage.
What Is Growing?
In the context of capers, “growing” refers to the comprehensive process of cultivating the caper plant, including the planting, nurturing, harvesting, and processing of the buds. Growing capers requires a keen understanding of their specific needs in terms of climate, soil, and care. As a hardy perennial, the caper bush is well-suited to arid environments, making it a valuable crop for regions with limited water resources.
Successful cultivation not only ensures a bountiful harvest but also contributes to the preservation of this storied ingredient, enabling culinary enthusiasts and professionals alike to enjoy its rich flavors.
History and Origins
The caper bush has ancient roots, with evidence of its use dating back thousands of years. Originating in the Mediterranean region, particularly around the islands of Crete and Cyprus, capers were highly prized by the Greeks and Romans for their culinary and preservative qualities. Ancient texts, including those by Pliny the Elder, describe the caper as a delicacy, showcasing its longstanding significance in human culture.
Throughout the centuries, capers spread across Europe and into other parts of the world, adapting to various climates and culinary traditions. Today, they are cultivated in countries such as Italy, Spain, France, and even parts of the United States, where their unique flavor continues to enhance an array of dishes.
Production and Processing
Cultivation
The caper plant thrives in warm, dry climates with well-drained soil. It can be propagated from seeds or cuttings, with seeds requiring a stratification period for optimal germination. When planting, consider spacing the plants adequately to allow for their sprawling growth habit.
Harvesting
Capers are typically harvested in late spring to early summer, just before the flowers bloom. The buds should be picked while they are still tight and green, as this is when they possess the most flavor. Harvesting is labor-intensive, as the buds must be collected by hand to avoid damaging the plant.
Processing
Once harvested, capers are usually brined or packed in salt to preserve their flavor and extend shelf life. The brining process involves soaking the buds in a mixture of water, salt, and vinegar, which enhances their tangy taste. Salt-packed capers require rinsing before use to remove excess salt, while brined capers are ready to use straight from the jar.
Quality and Grading
Factors Affecting Quality
The quality of capers is influenced by several factors, including size, color, and flavor intensity. Generally, smaller capers, often referred to as “nonpareil,” are considered the finest quality due to their delicate texture and pronounced flavor.
Grading Standards
Capers are graded based on a standardized sizing system, which classifies them into categories such as nonpareil, capote, and grande. Nonpareil capers are the smallest and most sought after, while larger varieties are often used in more rustic dishes where texture is less critical.
Buying Considerations
When purchasing capers, consider the following:
1. Type: Decide whether you prefer brined or salt-packed capers, as each offers a different flavor profile and uses.
2. Quality: Look for well-graded capers, with smaller sizes typically denoting higher quality.
3. Packaging: Check for integrity in packaging; jars should be sealed and free from any signs of damage.
4. Expiration Date: Always check the expiration date to ensure freshness.
Uses and Applications
Capers are a versatile ingredient, frequently used in Mediterranean dishes. Their pungent flavor complements a variety of foods, from seafood and poultry to pasta and sauces. Common applications include:
- Pasta Dishes: Capers add a salty, tangy punch to pasta sauces, particularly in aglio e olio or puttanesca.
- Salads: They can enhance the flavor profile of salads, providing a contrast to rich dressings and creamy ingredients.
- Meat and Fish: Capers are often paired with meats, especially in dishes like chicken piccata or veal saltimbocca, where their briny flavor cuts through richness.
- Garnishes: They serve as a delightful garnish for various dishes, adding a pop of color and taste.
Storage and Shelf Life
Proper storage is essential for maintaining capers’ flavor and quality. Brined capers should be stored in the refrigerator after opening, where they can last for several months. Salt-packed capers can be kept in a cool, dry place, but should be sealed tightly to prevent moisture absorption.
Both types of capers should be checked periodically for any signs of spoilage, such as off odors or discoloration. When stored properly, unopened jars can last up to two years, while opened jars should ideally be consumed within six months for the best flavor.
Common Misconceptions
1. Capers Are a Vegetable: Many people mistakenly believe that capers are vegetables. In reality, they are flower buds harvested from the caper bush.
2. All Capers Are the Same: The quality and flavor of capers can vary significantly based on size and processing methods, with smaller capers generally being more flavorful.
3. Capers Are Only for Mediterranean Cuisine: While capers are foundational in Mediterranean cooking, their unique flavor can enhance dishes across various
