Beef Stroganoff

Sour cream can curdle if added directly to hot liquid. To prevent curdling, temper the sour cream by stirring a little of the hot liquid into it and then adding the warmed sour cream mixture to the pan. Buttered egg noodles are the classic accompaniment to this recipe. Add noodles to boiling water at the same time the onion goes into the pan in step 4, so that the noodles and stroganoff will be done at about the same time.
