Heat olive oil in a large saucepan over medium heat; cook and stir jalapeno pepper and garlic until garlic is lightly cooked, 3 to 5 minutes.
Mix salt, cumin, black pepper, cardamom, coriander, cinnamon, paprika, cloves, and nutmeg together in a bowl; stir into jalapeno pepper mixture until evenly coated. Stir in tomato sauce and tomato paste; lower heat and simmer for 20 minutes.
Pour milk into tomato mixture and stir in chicken; cook until chicken is heated through, about 5 minutes. Sprinkle cilantro over chicken mixture.
