Ingredients

• 8 quail eggs (optional)
• 4 slices firm white bread, crusts discarded ((1/2-inch-thick)
• 1 cup whole milk
• 1 medium onion, chopped
• 2 garlic cloves, chopped
• 3 1/2 tablespoons vegetable oil, divided
• 1/2 teaspoon turmeric
• 3 -4 tablespoons bottled crema (aji amarillo or aji mirasol paste)
• 2 cups reduced-sodium chicken broth
• 1/2 cup grated parmigiano-reggiano cheese
• 1/2 cup walnuts (1 1/2 oz)
• 8 small chicken breast halves, with skin and bone (5 1/2 lb total)

Instructions

1. Garnish: pitted black Peruvian or Kalamata olives, halved; lime wedges (preferably Key limes).

2. Preheat oven to 400°F with rack in middle.

3. If using quail eggs, cover with cold water in a very small saucepan. Bring to a simmer and cook, covered, 5 minutes. Rinse eggs under cold water to stop cooking, then peel.

4. Soak bread in milk until softened, then mash with a fork.

5. Cook onion and garlic in 1 1/2 Tbsp oil with turmeric and 1/4 tsp salt in a 12-inch heavy skillet over medium heat, stirring occasionally, until softened. Stir in chile paste and bread mixture and simmer, stirring occasionally, until very thick, 3 to 5 minutes. Stir in broth and cheese and simmer 1 minute. Carefully transfer to a blender with walnuts and blend until very smooth, about 1 minute (use caution when blending hot liquids). Transfer sauce to a medium saucepan and keep warm, covered, over very low heat, stirring occasionally.

6. Pat chicken dry, then season with 1 tsp salt and 1/2 tsp pepper. Heat 1 Tbsp oil in a 12-inch heavy nonstick skillet over medium-high heat until hot, then brown half of chicken, skin side down first, turning once, about 8 minutes total. Transfer, skin side up, to a 4-sided sheet pan. Pour off oil from skillet and wipe clean, then brown remaining chicken in remaining Tbsp oil in same manner.

7. Roast chicken in oven until just cooked through, about 15 minutes.

8. Halve quail eggs lengthwise.

9. Spoon some of sauce onto a large platter, then arrange chicken on top. Garnish with quail eggs and serve with remaining sauce on the side.
