Tom and Jerry Cocktail

For Tom and Jerry Batter, beat egg whites and crème of tartar in a large bowl with an electric mixer on medium speed about 1 minute or until soft peaks form (tips curl); set aside.

Whisk together egg yolks and granulated sugar in a large bowl until thoroughly combined. Add vanilla and rum, mix until combined, with a spatula, gently fold in egg white mixture; cover and keep refrigerated until ready.

For drink, bring water to a boil in an electric tea kettle or saucepan. Add boiling water to a 6-oz. mug until mug is warmed; discard water.

For each serving, stir together 2-oz. prepared Tom and Jerry batter, rum and cognac in warmed mug. Top with hot milk. Garnish with nutmeg, if desired.
