2 ounces espresso

Two ounces foam gently layered on top.

That's it.

By far my favorite drink.

2 oz. of fairly dry foam would represent quite a bit in volume. Is this weight simply a guess-timation based on cup size, in relation to espresso volume or what?

A treat I find awesome and is also the only way I will consume coffee in a cold'ish state is a caramel con panna. Made by extracting a double ristretto (maybe 1-1.5 oz. MAX) stirred into 1/2 oz. of rich caramel sauce (Monin or Ghirardelli) and topped with fresh whipped cream.

I retract, 2 heaping table spoons of foamed milk.
