1 jar of red lumpfish caviar*
1 16 oz. container of sour cream
1 white onion (preferably vidalia), diced
Empty container of sour cream into a bowl. Gently fold in the diced onions and caviar until well mixed. Chill for several hours. Goes great with crackers, toast points, or baguette slices.
*You can use the black lumpfish caviar - the taste is the same - but the black results in a grayish green dip which is far less appealing than the pink dip you get with the red caviar. And most importantly, do not use really good expensive caviar for this - save the beluga for a special occasion.
