Bourbon for the Eggnog.
Tom & Jerrys are a snap.
Beat a dozen egg yolks, a smidge of salt, about two tablespoons of baking soda and a two pound package of powdered sugar together very well. The longer you beat it the lighter in color and stiffer it’ll get. I beat mine about ten minutes with an electric mixer. Add some good quality vanilla, maybe a tablespoon, and mix yet until it’s completely blended in. Pour into a covered tupperware and freeze until very firm. NOTE: it will never freeze super solid.
Using large mugs add a shot each of dark rum and brandy or bourbon then two ice-cream scoops of the frozen batter to each mug and fill with very hot water. Top with a sprinkle of nutmeg, not a lot.
As Haleysgold has suggested, they pack a punch.
