Achieving the perfect micro foam for a Flat White requires practice and attention to detail. Start by using cold, fresh milk and purging the steam wand to remove any excess water. Submerge the steam wand just below the surface of the milk and position the steam pitcher at a slight angle to create a whirlpool effect. Steam the milk until it reaches a temperature of around 140-150°F (60-65°C) and has a smooth, velvety texture. Avoid creating large bubbles or overheating the milk, as this can result in a less desirable texture for your Flat White.
