I made some eggfruit nog the other day, by using an eggfruit in place of actual eggs. The yolky taste of the fruit makes a surprisingly close substitute and its vegan if you're into that sort of thing. Here's what I put:
1 egg fruit
1 1/4 c soymilk (sweetened, otherwise add sugar to taste)
1/4 t nutmeg
1/2 t cinnamon
1/4 t salt
1 t vanilla extract
Blend until smooth, add more soy milk if too thick. I didn't have any on hand, but if you throw in some bourbon I think it would taste even more like the real thing.
