Latte with Foam

I admit it: I am one of those yuppies who own a Keurig coffee machine. I know, I know: this makes me some kind of consumerist whore. But the darn thing brews single cups of coffee! And it makes great hot chocolate with no lumps in less than a minute! I mean, come on: no more lukewarm coffee, and fast hot chocolate? Surely I can be forgiven my sin on this one...

Anyway, the latte recipe implies using this fancy-schmancy coffeemaker. But I'm sure you could modify it if you wanted.
