If you have a 12-oz. pitcher, fill it with about 10 oz. of milk; 14 oz. will do in a 20-oz. pitcher. In either case, this is about a pinky's width below the bottom of the nozzle.Angle the pitcher and so that your steamwand is aimed diagonally into the milk's lower right quadrant
Tap the pitcher on a flat surface to break any remaining bubbles. Give it a few swirls to equalize the texture. The consistency should resemble wet paint, or “white chrome,”.
Submerging the wand will create the “whirlpool” motion necessary to break down bubbles and create microfoam.Once your milk has reached the appropriate temperature, turn off the steam wand. Purge it, and give it a few vigorous wipes with a clean towel.
To achieve exquisite latte art, begin pouring your milk slowly. Start with a narrow stream to avoid breaking the espresso's crema. Once your drink is about half full, lower your pitcher's spout so that it's almost touching the liquid. This will guarantee strong contrast. Continue pouring.
