The Coffee Float

Take a nice tall glass, preferably chilled. Add about 2 thumbs widths of milk to the glass, probably about 3 oz, but I rarely measure.
Add one teaspoon of instant coffee, level rounded or whatever your taste may be to the milk, do not stir. You can also subsitute 2 oz of very strong coffee.
Slowly pour Cola (Pepsi, Coke or whatever) over the whole mixture being mindful of the foam.
After your glass is just about full take a spoon and gently stir the whole concoction. You should notice a "head" of dense foam beginning to appear at the top of the glass. This is good.
After the foam has settled a little bit enjoy.
