An espresso's deep flavor is produced by forcing hot water through a finely packed, dark-roasted grind. It might be sipped or downed in one gulp, with or without sugar.
Unscrew top compartment of a stove-top espresso maker. Remove central canister; fill with fine- ground dark-roasted coffee.
Fill bottom compartment up to valve with cold filtered water. Screw components back together. Heat over medium-high heat until pot begins to gurgle and hiss. Serve 1/4-cup portions in espresso cups.
