I don't believe you can make a good
caffè in an automatic espresso machine without spending a lot more money, and even then it's not easy. On the other hand, every home in Naples has a simple
moka,
caffettiera, or
macchinetta that makes pretty good coffee. You can find them locally in lots of places, and they look like
this.
You could always get them a gift certificate for Caffè Italia, if they don't live too far from Harlem and Diversey. Or maybe just track down some coffee from
Passalacqua for them. The latter would be an inspired gift.
