You can hone your latte art skills without using milk by practicing with dishwashing liquid. Fill the pitcher halfway with cold water, then add a single drop of concentrated soap. Position the liquid-filled pitcher under the steam wand and engage it. The mixture will mimic the consistency of milk, allowing you to practice creating microfoam. Move the pitcher slowly downward until you achieve the desired temperature, replicating the motions involved in frothing milk. This creative technique provides a valuable opportunity to refine your pouring and latte art skills, even when traditional milk is not available. Happy practicing!
