of course you tell them that if you don't know how to do it.
If you do know then its simple!!!
Same as if they came into a Starbucks and asked if you could give them the Grand Unified Theory. If you don't know how to do it then you don't.
However, although the GUT is still elusive to all physisists an Iced Capuccino isn't that hard!!! http://www.coffeeforums.com/viewtopic.p ... e36221df76
not necesarily. depends on how long you want the foam to stay put. Espresso by itself with as much suger as you wish (meaning not at all even) foams up very nicely and lasts fro almost half an hour-good enough to serve. Of course Nescafe Frappe you can make a foam that will last for eternity!!!
really I suppose the only difference between an iced capp and an iced latte is the proportion of espresso to milk/froth. When someone orders an iced capp that always said to me "I want cold with alot of espresso". Usualy did half milk half espresso for capps.
