Rascally radishes, members of the mustard family, meet their match with salty anchovies and capers; roasting tames all three (and a squeeze of lemon brightens the lot), transforming them into a sublime side dish.
Preheat oven to 375 degrees, with rack in upper third. Toss together radishes, capers, anchovies, garlic, and oil; season with salt and pepper. Spread out mixture in a small roasting pan. Roast, stirring once, until radishes are shriveled and fragrant, 30 to 35 minutes. Serve warm with lemon.
