Brew 1 or 2 shots of espresso using an espresso machine or substitute with a stovetop espresso maker or strong brewed coffee.
While the espresso is brewing, heat the milk. Pour the milk into a small stainless steel milk jug or pitcher. Use enough milk to fill about 2/3 of the jug to allow room for steaming.
Steam the milk using an espresso machine or a frother, positioning the wand just below the surface, frothing with a small amount of air, and gradually moving it downward for even heating.
Continue steaming until the milk expands slightly. The ideal milk temperature for a flat white is around 150-155°F (65-68°C). Be careful not to overheat or oversteam the milk, as it can affect the taste and texture.
Pour steamed milk over espresso shots, starting close to the surface, pouring slowly, and gradually raising the jug for latte art if desired.
Serve immediately and enjoy your flat white coffee!
