Steam, then peel and blend in your blender:
1 medium sized pumpkin
2 sweet potatoes, peeled
1 cube butter
half-and-half as needed, to keep the blender from bogging down
salt to taste
1 C slivered almonds
Serve soup garnished with tosted almonds, 1 t sour cream, & nutmeg.
The trick to this soup is a good blender and to blend the pumpkin and sweet potato until they are velvety.
