Pour 2 tsp instant coffee granules, 2 tsp (or more) sugar, and 2 tbsp water into a small mason jar with a thigh-fitting lid or cocktail shaker. Close the lid tightly and shake vigorously for 1-2 minutes until very foamy.
Fill a tall glass halfway with ice cubes. Pour the froth into the glass and slowly top off with cold water. Leave room for heavy cream or milk, if using.
Make it with milk instead of water (except for the little bit in the beginning) and you'll have a frapógalo - frappe float.
Don't skimp on the shaking step. The stronger you shake, the more delicious the foam.
It's damn near impossible to get all the foam out of the jar...so pour some water in it, put the lid on, and shake. Pour contents into your glass, repeat as necessary.
No shortcuts! If you try to add all of the water and then shake, you'll end up with just the foam.
Take it to the next level and add a shot of Baylies, Kahlúa, or a scoop of vanilla ice cream.
