Opa George's Wild Rice

Combining wild rice, mushrooms, nuts, green onions, and sour cream, my father's recipe goes very well with any game dish. The recipe calls for fresh or dried morel mushrooms, which give the recipe its best flavor, but any type of mushroom, fresh or dried, should work well. Similarly, he always used chestnuts, but we have found that pecans and hazelnuts (and, probably walnuts or cashews) work just as well. Preparation time depends on whether one is using dried mushrooms or not.
