The process involves aerating cold milk until it forms a thick, stable foam, similar in texture to whipped cream but lighter. A frother, either handheld or integrated into an appliance, is the tool used to achieve this transformation. Successfully creating this topping enhances beverages like iced coffee and cold brew by adding a creamy, textural element.
Employing this method offers a versatile alternative to traditional dairy-based creamers or sweeteners. It allows for controlled customization of beverage textures and flavors, catering to dietary preferences with options like non-dairy milks. This technique has become increasingly popular in specialty coffee preparation due to its ability to replicate coffeehouse-style drinks at home.
