Well, we bought a little carton of the Silk kind to satisfy my curiosity and we both love it! Especailly when we put it in our coffee instead of our usual almond milk. Mmm. Here's how I've been making ours lately, it's been extra necessary due to moving/packing/driving.
Using the scoop that came with our french press:
-4 scoops coffee
-2 scoops cocoa powder (a natural kind is best, but as long as you make sure it's just chocolate and not a bunch of crazy ingredients it should be fine)
-2 scoops natural cane sugar
-Silk eggnog, as much or as little as you'd like
Heat up 4 cups of water, pour it on the mixture, stir once, place french press lid on and wait 5 minutes. Plunge, pour in your eggnog, and enjoy!
