• 2 lb. ripe plum tomatoes, finely chopped
• 1/4tsp. dried thyme
• 2 bay leaves

• Sea salt (or coarse salt) to taste

• 1/2c. slivered blanched almonds
• 1/4c. capers, rinsed
• 1/4c. chopped Italian parsley
• 1/4c. packed fresh cilantro leaves

To prepare chiles: Leaving the stem end intact, make a lengthwise slit in each and remove seeds and veins, being careful not to break the pepper. In a pan big enough to submerge peppers, combine water, piloncillo, cinnamon, vinegar and 1/2teaspoon salt, and boil to dissolve sugar. Reduce heat and simmer 5 minutes. Add the chiles, cover and remove from heat. Let chiles soak until soft, 15 to 20 minutes. Transfer to absorbent towels.

To prepare picadillo: Heat olive oil in saucepan. Add the 1 cup onion and cook until translucent, about 2 minutes. Add the garlic and cook 1 minute. Add the tomatoes, thyme and bay leaves, stir and simmer until the mixture begins to dry out, about 15 minutes. Add raisins and cook about 4 minutes. Add the chicken and cook to meld flavors. Stir in olives, almonds, capers, 1/4cup cilantro, parsley and mint. Remove from heat, let cool.

Carefully stuff chiles with picadillo and place the chiles, just touching, in a lightly greased baking dish. Cover and bake until heated through, about 15 minutes.

Meanwhile, prepare the sauce: In a small saucepan over low heat, combine the crema, 1/2cup onion and 1/2teaspoon salt, bring to a bare simmer and cook for 5 minutes. Strain, add the 1/4cup cilantro and keep warm.

To serve, place one chile on a plate, top with sauce.
