Capers, those tiny, briny, and intensely flavorful buds, are a staple in Mediterranean cuisine and beyond. But what are they actually good for? Far from being mere garnishes, capers offer a surprising array of culinary applications and potential health benefits. This article delves into the world of capers, exploring their history, nutritional profile, uses in the kitchen, and potential positive impacts on your well-being.
A Brief History and Origin of Capers
The caper bush, Capparis spinosa, is believed to have originated in the Mediterranean region, with evidence of its use dating back thousands of years.
