White Russian Cocktail - 1 jigger (1.5 oz or 3 TB) vodka, 1 jigger heavy cream , 1 jigger Da Vinci's Sugar-Free Kahlua-Flavored Syrup, There are 2 variations in the amounts of the main ingredients of a White Russian. The first has 2 parts vodka to one part each of the other 2 ingredients. The other has equal parts of all 3. If I want a cocktail that is less rich, I will substitute water for half of the cream. This would reduce the carbohydrate to half a gram and the calories to 174.
