Capers are one of those ingredients that remind us just how hungry human beings can get.
They're buds of a bush found in Mediterranean countries and parts of Asia. Handpicked, the buds are usually dried, then preserved in a salt brine or dry salt.
Much of the salt is washed away when capers are rinsed before use in cooking.
Capers are a distinctive element of Italian cuisine, especially Sicilian dishes, like swordfish with a sauce of capers, orange and olives. The classic chicken piccata usually incorporates a healthy dose of capers in its lemony sauce.
Size matters: Petite nonpareil capers, the smallest commercially available, have a reputation for the most delicate flavor. If allowed to flower, capers will produce a fruit referred to as a "caper berry" that is sometimes picked and pickled.
Here, capers add salt and depth of flavor to a simple but luxurious dish of roasted mushrooms. It's a killer side dish alongside grilled steak or a bracingly fresh green salad.

2 teaspoons fresh lemon juice
1/4 cup chopped flat-leaf parsley
Preheat oven to 450 degrees with rack in middle.
Toss mushrooms with capers, garlic, oil, and 1/8 teaspoon each of salt and pepper in a 1 1/2 - to 2-quart shallow baking dish. Top with butter and roast, stirring occasionally, until mushrooms are tender and golden, 15 to 20 minutes. Stir in lemon juice and parsley.
