How to use a milk steamer effectively for frothing and heating milk?

To use a milk steamer effectively for frothing and heating milk, first fill the steaming pitcher with cold milk up to about halfway. Place the steam wand just below the surface of the milk and turn on the steam. Keep the wand at a slight angle and position it off-center in the pitcher to create a whirlpool effect. Move the pitcher in a circular motion to evenly heat and froth the milk. Stop steaming when the milk reaches the desired temperature, usually around 150F. Clean the steam wand and pitcher after each use.
