I don't know if this a good one but it a standard here in the South. Not a recipe, but a general rule of thumb. Per each ramekin, two tablespoons butter, two eggs, two tablespoons heavy cream. Add in the order listed. 350 oven for about 10 minutes. Add your favorite grated cheese and cook about 1 minute longer or until cheese is melted. Ovens vary, so meke sure you test it before a party.
