In a small bowl, beat egg yolks until thick; set aside.
In a large bowl of your electric mixer, beat egg whites until stiff peaks form. Using a spatula, fold 1/2 cup superfine or granulated sugar slowly into the prepared egg whites.
Using your rubber spatula, fold the beaten egg yolks into the egg whites with the sugar.
Add the remaining 1 3/4 cups superfine or granulated sugar, salt, and vanilla extract.
Still using your rubber spatula, slowly and gradually fold in the powdered milk.
Store, covered, in the refrigerator, and use as needed. Will keep up to one (1) week in the refrigerator. Mixture will probably separate in the refrigerator. No problem - just stir and use. The drink will still turn out frothy and delicious.
Serves many.
How To Make Tom and Jerry Drinks:
Make each individual serving in a large cup or mug:
Place 1 to 3 heaping tablespoons of prepared Tom and Jerry batter into each cup (amount depends on size of cup and to your taste preference). Our family uses 3 heaping tablespoons for an 8-ounce cup.
Add boiling water to fill cups to 3/4 full.
Add 1 ounce of either rum, brandy, or whiskey to each cup (use the amount of liquor you desire - for children, leave the liquor out).
Stir until well blended. Sprinkle with nutmeg.
Serve and enjoy!
* I know that they say you should not use raw eggs anymore! We do and have for many, many years. Just be sure and purchase very fresh or pasteurized eggs to use for this wonderful drink.
** If you can't find superfine sugar (also called Baker's sugar), use regular granulated sugar. I like to use the superfine sugar because it dissolves easier.
