Capers are the unripened flower buds of the Capparis spinosa bush, a hardy plant native to the Mediterranean and parts of Asia. These small green buds are rarely eaten raw due to their intense bitterness; instead, they are cured in salt or a vinegar brine to develop their signature tangy, salty, and slightly floral flavor profile. Understanding how to manipulate this brine is essential for any chef looking to add a punch of acidity to savory dishes.
Requirements for Working with Capers
- Capers: Choose between vinegar-brined or salt-packed varieties based on your recipe needs.
- Fresh Water: Required for rinsing and soaking to control the sodium levels.
- Fine Mesh Strainer: To effectively drain and wash the small buds.
- Paper Towels: Necessary for drying capers, especially if you plan to fry them.
- Cutting Board and Knife: For mincing or chopping larger caper varieties.
Step 1: Selecting the Right Size and Variety
Capers are graded by size, and the size significantly impacts the flavor and texture. The smallest ones, known as Nonpareilles, are highly prized for their delicate texture and concentrated flavor. Larger varieties, such as surfines or grands, are more acidic and have a meatier texture. Additionally, consider the curing method: salt-packed capers tend to have a more authentic floral taste but require thorough soaking, while vinegar-brined capers offer a sharper, more convenient acidic kick.
Step 2: Preparing and Rinsing the Buds
To manage the briny profile, you must prepare the capers correctly. For vinegar-brined capers, place them in a fine mesh strainer and rinse under cold water to remove excess acidity. For salt-packed capers, the process is more involved. Soak them in a bowl of cold water for at least 15 to 20 minutes, changing the water once. This removes the harsh exterior salt while preserving the internal flavor. Always taste a bud after rinsing to ensure the salt level is appropriate for your dish.
Step 3: Incorporating Capers into Cold Dishes
Capers excel in cold applications where their brightness can cut through rich or fatty ingredients. For a classic Mediterranean touch, add whole Nonpareilles to a smoked salmon platter or a tuna salad. If you are making a tartare or a vinaigrette, roughly chop the capers to release their oils and distribute the salty flavor more evenly. Their briny nature acts as a natural flavor enhancer, often reducing the need for additional table salt.
Step 4: Cooking and Frying for Depth
In hot dishes like Chicken Piccata or Pasta Puttanesca, capers should be added toward the end of the cooking process. High heat for extended periods can turn them bitter and mushy. A professional technique to elevate the briny profile is to deep-fry them. Pat the rinsed capers completely dry and drop them into hot olive oil for 30 seconds. They will burst open like tiny flowers and become incredibly crispy, providing a salty, umami-rich garnish for fish or roasted vegetables.
Conclusion
The briny profile of capers is a powerful tool in the kitchen, offering a unique combination of salt, acid, and floral notes. By carefully selecting the size, properly rinsing the curing agents, and choosing the right moment to add them to your recipe, you can transform a simple meal into a gourmet experience. Whether used as a subtle background note or a crispy star garnish, capers are indispensable for balanced, flavorful cooking.
