How to make a cappuccino
Make your espresso in a moka pot.
Fill the lower chamber of your moka pot with water and set the strainer on top. Fill the strainer with your espresso-ground coffee and wipe away any grounds on the edge.
Screw on the top of the pot and set it on your stove over low heat. Heat the espresso until you hear gurgling and the water boils.
