I saw a dessert on Food Network made out of coffee and started playing with that idea. I have a small, electric ice cream maker and just wanted to make a small amount that would use left over coffee. Here is the recipe that I came up with. It serves about 4 people.
Hot Damn Coffee Granita
1.5 c coffee, the stronger the better
1/2 c fat-free Half and Half
1/2 c sugar
1 T cocoa
1.5 oz Hot Damn Cinnamon Schnapps
1 tsp vanilla extract
Mix all ingredients together and place in a small, electric ice cream freezer (instructions will vary by freezer). For me, it took about 20 minutes to freeze. You can also pour it into a casserole dish and place in the freezer, then stir every 45 minutes or so to disperse the ice crystals. It won't freeze real hard because of the alcohol in it. You could substitute other alcohols with a little experimenting. I can tell you we won't be tossing out any coffee. Here is a good article on theKitchn with some more ideas for making the most of left over coffee.
Note: I tried this recipe with peppermint Schnapps and it was quite tasty. I upped the cocoa to 2 T and added 3 oz of Schnapps instead of the cinnamon. It was really good!!
