Southwestern Turkey with Garlic-Ancho Chili Paste and Gravy

Preheat oven to 350 °F. Separate heads of garlic into individual cloves (do not peel). Pierce each clove once with toothpick. Scatter garlic on baking sheet; roast until tender and beginning to brown, about 25 minutes. Cool 5 minutes. Peel garlic, cutting hard tip off each clove. Pack enough garlic into 1/2-cup measuring cup to fill (about 40 cloves); reserve any remaining garlic. Blend 1/2 cup garlic in processor to form course puree. Meanwhile, place chilies in small saucepan. Add enough water just to cover. Simmer over medium-low heat until chilies are soft and most of water evaporates, about 15 minutes. Add chili mixture, oil, cumin, and honey to garlic in processor. Puree until smooth. Season with salt and pepper. (Can be made 1 week ahead. Cover paste and garlic; chill.)
