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.

OPT:
[+] 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.;
[+] Allow the coffee to cool down before cutting the espresso into pieces. You can also use a cup or mug instead.;
[+] Pour some milk over the top of the coffee to fill the lower chamber with milk. Fill a shaker, such as a smart-shot cappuccino or a jug or pitcher, with enough milk to fill the bottom of the shaker.;
[+] Place the mug on top of the pot using a sturdy tea-cloth. Position the mug over your espresso strainer, then lower the strainer and close the lid.;
