Hot cocoa! Yum! It's not just for the holidays, you know. I make it frequently. My recipe:
1/2 cup cocoa powder
1/2 cup baker's (or regular) sugar
3 Tbsp. powdered vanilla
1/4 tsp. salt
1/4 tsp. cinnamon
1/4 tsp. nutmeg (freshly grated if possible)
pinch of piment d'espelette (or cayenne pepper)
Mix all the ingredients and store in a Mason jar or other container. It makes about a half dozen servings.
To prepare, put 3-4 Tbsp. in a cup, spritz a little hot water into it and stir to incorporate. It should look like a thick espresso. Then just foam milk as usual and pretend you are making a latte. Yum!

*if you don't have powdered vanilla, you can add a few drops of liquid extract with the water instead.
*The lazy way is to just squirt an equal amount of chocolate syrup into the cup and prepare the same way. Easy! Although not quite as tasty.... '_'
