For rice: heat water and rice to boiling in a saucepan. Reduce heat to low, cover and let simmer for 10-15 minutes or until water is completely absorbed.
For mango puree: combine ingredients and blend in blender or with a stick blender until smooth.
Beat eggs in a greased 1 1/2 quart casserole. Stir in remaining ingredients and mix well. Fold in mango puree.
Bake uncovered for 45 minutes, stirring every 15 minutes. Remove from oven (it will not seem done) and let rest for 15 minutes. Serve warm or refrigerate for 3 hours or overnight to serve cold. Garnish with coconut before serving.
**for an elegant presentation: triple mango puree but do not add it to the pudding. Bake pudding as directed adding 1/2 cup additional milk. Cool completely. Then layer pudding and mango puree into a tall wine glass. Serve chilled and garnish with coconut.
