As seen in Food and Wine's Eggplant Caponatina recipe.
On the coast of Sicily in the town of Salina, Antonino Caravaglio has made a life out of cultivating a flowering bush whose buds lend their savory flavor to dishes the world over. While this plant produces a lovely pink flower, the appearance of it marks the passing of a caper's life - it is the bud of this flower which Caravaglio harvests and buries in salt for 20 days which becomes the caper we know. The capers are then aged for 2 months, allowing the floral flavor to blossom.

These capers are delicious - we buy them by the kilo and keep them in the fridge in a pyrex. If you're not used to using salted capers, just make sure to soak them in warm water before adding to whatever you're cooking.
