Step 1

Cook onions, bell pepper, garlic, ginger, spices: Heat oil in a large sauté pan over medium heat. Add onions and bell pepper cook, stirring occasionally, until soft, about 5 minutes.Add the garlic and ginger and cook for another minute.Add the curry powder and cumin, cook for a few more minutes. The spices will absorb some of the oil, so if anything begins to stick too much to the bottom of the pan, add a little more oil to the pan.

Step 2

Add the vinegar, coconut milk, and one of the two chopped mangoes to the pan. Increase the heat and bring to a boil, then lower the heat to maintain a low simmer for about 15 minutes, stirring occasionally.

Step 3

Purée sauce: Remove pan from heat. Scoop the sauce into a blender. Purée the sauce, pulsing until smooth. Return the sauce to the pan.

Step 4

Add chicken pieces and raisins to the pan. Return to a low simmer. Cover the pan and let cook for 8-10 minutes. Chicken should be just cooked through. Use a knife to cut open the largest piece to check.

Step 5

Add remaining chopped mango to the pan. Stir in the cream, if using. Let cook at a very low temperature for another minute or two, uncovered. Do not let boil! Or the cream may curdle.

Step 6

Adjust seasonings: If a little too sweet, add a little more vinegar. If not sweet enough, you can add a dash of sugar. Add salt and pepper to taste.Serve over rice. Garnish with cilantro.
