I read once that squash (butternut) is better nutritionally than pumpkin, although the difference is pretty minor, especially once they've been made into pies. According to nutritiondata.com, a serving of (plain) butternut squash has only 82 calories, plus huge amounts of vitamin A, and a substantial amount of vitamin C. Pumpkin, on the other hand, has fewer calories (49), but also half the vitamin A and C.
The filling for the pie (and its twin) above consists of:
- 2 cups of cooked, pureed butternut squash
- 1 can of evaporated milk (not sweetened condensed)
- 1/2 cup white sugar
- 1/4 cup brown sugar
- 1 or 2 Tablespoons molasses
- 2 teaspoons pumpkin pie spice mixture (from Penzey's Spices)
- pinch of salt
- 2 eggs
Mix together and bake (350 degrees) in two partially pre-cooked piecrusts for 30-40 minutes.
The recipe is supposed to make just one pie, but I've always found that it makes too much for a single pie, and it cooks more quickly, with less mess (I always spill some of the filling over the edge, messing up the pie plate and the oven), if I divide it into two pies.
