I tried to make beef stroganoff tonight, but the sour cream (or the half & half) separated and was gross. I did add 3 Tbsp. sherry to the whole thing (*after* everything else was in - consomme, mushrooms, beef, sour cream, half & half, etc.). Could the sherry have made it separate? I have seen stroganoff recipes that call for alcohol, such as cognac, so I would think there has to be a way to make it not separate. If anyone has overcome this or has ideas, please help! thanks!
