jar capers
Capers are low in calories but rich in antioxidants, particularly quercetin and other polyphenols, and contain modest amounts of vitamin K and iron. Their high sodium content from brining is significant and should be considered in dietary planning.
About
Capers are the pickled unopened flower buds of Capparis spinosa, a thorny shrub native to the Mediterranean and parts of Asia. The buds are harvested by hand at a stage just before flowering and range in size from nonpareil (smallest, 7–8 mm) to surfines (larger varieties). They are then cured in salt and vinegar brine, which gives them their characteristic salty, briny, tangy flavor with herbaceous and slightly astringent notes. Capers undergo a fermentation process during brining that develops their complex flavor profile and distinctive peppery, lemony undertones. The texture is firm and slightly crunchy, and the small dark green buds become wrinkled and concentrated in flavor as they mature in their brines.
Jar capers are the preserved form sold in glass jars, either packed in salt brine or vinegar solutions, offering convenience and shelf-stability while maintaining their traditional brined character.
Culinary Uses
Capers function as a piquant garnish and flavor accent across Mediterranean cuisines, particularly in Italian, French, Spanish, and Greek cooking. They are essential to dishes such as French remoulade, Italian caponata, and Spanish escalivada, where their briny intensity cuts through rich ingredients. Commonly used in smoked fish preparations, salads, pizzas, and pasta sauces, capers provide a burst of salty, vinegary complexity. They pair exceptionally well with anchovies, olives, and lemon, and complement poached fish, chicken, and vegetable preparations. Capers should be rinsed before use to remove excess salt or vinegar, and are typically added near the end of cooking to preserve their texture and bright flavor.
