Adapted from Drinking Distilled: A User's Manual by Jeffrey Morgenthaler This recipe can easily be scaled up. I ended up tipping a little more tequila into the eggnog, which is the higher amount given. You can start with the smaller, and use more, to taste. Jeffrey recommends using anejo tequila and amontillado sherry, and if those are available, I suggest using them, too. For those who want or need to avoid raw eggs, you can use pasteurized eggs in this recipe.
