I found this recipe in the New York Times over 20 years ago. I was sitting in an airport waiting for a flight and happened to pick a copy of the paper. I am so glad that I did. This a special occasion meal at our house.
Place the banana, mango and egg in a blender and puree, slowly adding the garam masala. Place the nuts on another plate.
Remove from the blender and place the fruit-spice mixture on a plate.
Salt the chicken to taste. Dip each piece in the fruit-spice mixture, then press into the nuts.
Saute` in the butter until golden, about 12 minutes, turning once. Drain on paper towels and serve.
Roast the ingredients, except the nutmeg, one by one in a dry skillet over medium heat until fragrant. Allow to cool, then remove and discard the papery shells of the cardamom and place the seeds, with the other ingredients, in a spice grinder or electric blender and pulse to a fine powder. Mix in the grated nutmeg. Can be stored in an airtight jar. Makes about 10 tablespoons.
