I love the fall and all the colors and its when I start to crave anything pumpkin. In this recipe you can use canned pumpkin just omit the nutmeg, brown sugar, and pumpkin pie spice. Use about 2 cups canned pumpkin.
Heat the oil in a large skillet. Add the pumpkin and half of the onions. Cook over moderately high heat stirring frequently until the pumpkin is tender. About 7 minutes.
Stir in half the wine, nutmeg, pumpkin pie spice, brown sugar, salt and white pepper. Cook until most the liquid is evaporated. About 12 minutes.Remove from heat and puree in food processor. Set aside.
Place vegetable stock in a medium saucepan and bring to a boil. Reduce heat to low and keep warm.
In a large saucepan add the butter and bring it to a sizzle. Add the onions and rice and cook until the onions are translucent about 5 minutes. Add the remaining wine and let most evaporate.
