Ran out of espresso...but I had a brand new jar of NESCAFÉ, so I decided to try it out. I heated 1/2 cup of water and put about 3 tbsp of granules in...ninja'd it with hershey's syrup, a little sugar, crushed ice, and skim milk. Pretty good :) I read that you can just add the granules to the blender without dissolving them in water first. Next time I'll see how big of a difference that makes. And nope, no Guinness in the glasses LOL.
