Bangladeshi Chicken Korma

• 2 pounds skinless, bone-in chicken pieces (preferably dark meat)
• 1 teaspoon salt, plus more to taste
• 1 medium onion, peeled
• 1 1 1/2-inch knob of ginger, peeled and chopped
• 3 cloves garlic, chopped
• 1/2 cup whole-milk yogurt
• 4 to 6 green cardamom pods, cracked open
• 3 to 5 cloves
• 2 bay leaves
• 1 3-inch stick cinnamon
• 1/2 teaspoon sugar
• 1/2 teaspoon black peppercorns
• 2 to 3 small hot green chiles (optional)
• 2 tablespoons butter
• 2 tablespoons vegetable oil

1. Place the chicken in a medium Dutch oven, and season with 1 teaspoon salt.
2. Thinly slice 1/4 of the onion, and set aside.
3. Roughly chop the rest of the onion, and puree it in a blender with the ginger, garlic and 3 tablespoons of water, until smooth.
4. Add splashes of water to keep it moving, if necessary.
5. Combine the onion puree with the chicken, yogurt, cardamom, cloves, bay leaves, cinnamon and peppercorns.
6. Bring the mixture to a simmer over medium-high heat, stirring.
7. Cover the pot until the chicken releases its juices, 5 to 7 minutes.
8. Uncover the pot, and adjust the heat to maintain a gentle simmer.
9. Cook, stirring and flipping the chicken occasionally, until tender and the sauce is gravylike in consistency, about 35 minutes.
10. Adjust the thickness of the sauce by adding water or cooking it down.
11. Stir in the sugar.
12. Pierce the chiles with a knife, then add them.
13. Season to taste with salt.
14. Keep warm over low heat.
15. Heat the butter and oil in a small saucepan over medium-high heat.
16. After it foams, add the sliced onions, and cook, stirring, until they are richly browned, 3 to 4 minutes.
17. Season with a pinch of salt.
18. Add the onion mixture to the korma.
19. Serve with steamed basmati rice.
