With Lattes the portions are a little less strict. Pretty much you add your shot to a cup and fill the rest of it with steamed milk. So, say you have an 8oz cup, you add your shot which we'll say is about 1oz, so that means you should add about 6oz of milk. The amount of milk is really going to depend on your glass, so the Latte allows for more flexibility in its preparation.
No, no, no. Everyone knows that the proper way to make a latte is 100% espresso and 0% milk (in any form).
At the risk of repeating myself, may I say (once again) how much I enjoy the sheer, effervescent enthusiasm, cheerful camaraderie, and genuine goodwill that I find on this thread.
I could not agree more.
