Frothy milk is created by incorporating air into milk, resulting in a light and airy texture. This process is commonly achieved using a steam wand, frother, or whisk. The frothing process not only adds volume but also enhances the milk's sweetness and creaminess, making it a popular choice for beverages like cappuccinos and lattes. The ideal frothy milk has small, fine bubbles and a velvety consistency. Whole milk typically produces the best froth due to its higher fat content, while alternatives like almond milk or oat milk can also be frothed, though results may vary.
