Steam or froth the milk: Steam the milk with an espresso machine, or heat and then froth the milk using your method of choice (milk frother, French press, whisk or covered jar). It’s easiest to steam or froth 1 cup of milk for 2 drinks. Go to How to Steam Milk or How to Froth Milk for details on each.
Serve: Pour the milk into the center of the espresso, ending with light foam (using half the steamed or frothed milk for 1 drink).
