Capers
Introduction
Capers are the edible flower buds of the Capparis spinosa bush, harvested by hand before they have a chance to bloom. These small, pea-sized gems are most commonly found pickled or canned in a salty brine, which transforms their naturally bitter taste into a complex, tangy flavour profile. They are celebrated for providing a concentrated burst of acidity and saltiness that can brighten even the simplest of dishes.
In the Australian kitchen, canned capers are often categorised by their size, with the smallest known as non-pareils being particularly prized for their delicate texture and intense flavour. The larger varieties are equally useful, often chopped to release more of their pungent aroma. Their firm structure and distinctive dark green hue make them a staple garnish in modern pantry collections across the country.
These resilient shrubs thrive in arid, rocky environments, often seen clinging to limestone walls or seaside cliffs throughout the Mediterranean. This hardy nature contributes to the plant's unique chemical makeup, resulting in a bud that is packed with flavour-enhancing compounds. When selecting canned capers, a clear brine and firm buds are indicators of high quality and freshness.
Culinary Uses
Canned capers are a cornerstone of Mediterranean-inspired cooking, valued for their ability to provide savoury pops of flavour in a variety of textures. Before use, it is common practice to rinse them under cold water to remove excess brine, allowing their true floral and peppery notes to shine. They are frequently added toward the end of the cooking process to preserve their distinctive shape and sharp bite.
Their piquant flavour makes them an ideal partner for rich, fatty ingredients, cutting through heaviness with ease. They are an essential component of a classic smoked salmon plate, typically paired with cream cheese and red onion, and are equally vital in creating a zesty tartare sauce for fresh seafood. The synergy between capers, lemon juice, and olive oil forms the basis for many versatile vinaigrettes and marinades.
In traditional Italian cuisine, they are indispensable in dishes like pasta alla puttanesca or chicken piccata, where they simmer alongside tomatoes, olives, and garlic to create a deeply savoury sauce. In Australia, they are often scattered over wood-fired pizzas or folded into potato salads to add a sophisticated layer of seasoning. Their versatility extends to vegetarian cooking, where they provide a "meaty" umami quality to roasted vegetables and grain bowls.
Nutrition & Health
While small in size, canned capers are an excellent source of antioxidants, specifically flavonoid compounds such as quercetin and kaempferol. These phytonutrients are well-regarded in nutritional science for their role in supporting cellular health and managing oxidative stress within the body. Their inclusion in a meal adds a significant boost of flavour and bio-active compounds without contributing substantial calories or fats.
These brined buds also provide modest amounts of essential minerals and vitamins, including Vitamin K and iron, which contribute to healthy blood coagulation and energy metabolism. However, because they are preserved in a salt-based brine, they are a concentrated source of sodium. To enjoy their benefits as part of a balanced diet, they are best used as a flavourful accent or seasoning rather than a primary vegetable component.
The fermentation or pickling process used for canned capers can also support digestive health by introducing organic acids into the diet. When paired with healthy fats like extra virgin olive oil, the fat-soluble vitamins and antioxidants within the capers are more efficiently absorbed by the body. This synergy makes them a nutritionally strategic addition to salad dressings and vegetable-based appetisers.
History and Origin
The history of capers stretches back thousands of years to the ancient civilizations of the Mediterranean and the Middle East. Archaeological evidence suggests they were used by the Sumerians as far back as 2000 BCE, both as a food source and for their purported medicinal properties. Their ability to grow in poor soil and harsh climates made them a reliable resource for early coastal inhabitants.
Throughout the Middle Ages, capers became a valuable commodity in global trade, spreading from the Greek islands and North Africa to the rest of Europe. They were highly regarded by the Romans, who documented various methods for preserving the buds in vinegar and salt to ensure they could be enjoyed year-round. This tradition of preservation is what eventually led to the modern canned and jarred varieties found in supermarkets today.
Beyond their culinary use, the caper bush has historical significance in various cultures as a symbol of resilience. In ancient Hebrew texts, the caper bud was often cited as a metaphor for the enduring spirit due to its ability to thrive in the cracks of rocks. Today, while most production is concentrated in Italy, Morocco, and Spain, the global appreciation for this ancient seasoning continues to grow, cementing its place in both traditional and contemporary gastronomy.
