Duck Confit With Spicy Pickled Raisins

Using the tip of a knife or the sharp tines of a carving fork, prick duck leg skin all over. Rub with garlic (slices should stick to skin) and season with 1 teaspoon ground pepper and 2 tablespoons salt.

Preheat oven to 250°F. Arrange duck skin side down in a roasting pan or large Dutch oven and add 8 thyme sprigs, 4 chiles (or 1 teaspoon red pepper flakes), and 1/2 cup water. Cover pan with foil or lid and cook until fat is rendered (don't be surprised: there will be lots), about 2 hours. Turn duck skin side up and nestle it into rendered fat. Cover pan and continue to cook until meat is very tender and bones easily wiggle when pulled, 2–2 1/2 hours longer.

Meanwhile, bring vinegar, sugar, mustard seeds, rosemary sprig, remaining thyme sprig, 2 chiles (or 1/2 teaspoons red pepper flakes), 1 teaspoon salt, and 1 cup water to a boil in a medium saucepan. Reduce heat and simmer, stirring occasionally, until sugar is dissolved, about 3 minutes. Mix in raisins, remove from heat, and let cool at least 1 hour.
