Ages ago, I remember going to Joe & Eddies to have a Tom & Jerry with Jeff and Larry, each year at Christmas time.
Until now, I had not known exactly what was in the drink concoction.  Here's the drink recipe for you!
First you'll need to make the 
Tom & Jerry Batter.
Ingredients:
- 12 eggs, separated
 
- 1 teaspoon cream of tartar
 
- 2 pounds of sugar
 
- 2 ounces dark rum
 
- 1 teaspoon vanilla extract
 
Directions:
Whip the egg whites with the cream of tartar until they form stiff peaks.  In a separate bowl, beat the yolks with the dark rum, sugar and vanilla.  Once the mixture is liquefied, fold into the egg whites.
