I used recipezaar's change size script to adjust to 2 servings. I used brandy instead of the rum, since I'm not fond of rum. The final product is quite tasty, if a bit "fluffy". It reminded me of a chocolate mousse recipe I make often, just not frozen. I've seen a lot of eggnog recipes with the whipped egg whites and cream, but I think next I'll try one of the custard sorts of eggnogs. Having grown up on store bought eggnog, the fluffy texture is not quite what I had in mind. But it's delightful in its own right. I should have thought to take a picture! It was a lovely drink, too. Definitely a keeper of a recipe.
