Bring to pressure, then lower to medium-low and cook for 35 to 40 minutes. If you don't have a pressure cooker, use four cups water with two cups rice and chestnuts. Bring to boil, cover, lower heat to medium high and cook 35 to 40 minutes without peeking. Serve as a casserole. Also good as a stuffing for turkey.
Chestnuts are the lowest in fat of all nuts.
Combine flour, baking powder and salt. Add to fruit. Spoon into well-greased tube pan. Bake for about one hour in preheated 300 degree oven, until cake tests done. Cool in pan 10 minutes, then turn onto rack.
