Sour Cream Old-Fashioned Doughnuts with Vanilla Glaze. If you attempt doughnuts, let me warn you, there must be no wandering off to check email. Let your voicemail system answer the phone. And if the cat knocks a china vase off the mantel, leave it lay where the feline flang it. Unless the house is burning down, do not leave the stove. Or else your house could burn down.
