Espresso powder is a type of coffee that has been ground into fine particles, typically used for making espresso. It contains finely-ground roasted coffee beans and can also include sugar or other flavorings depending on the brand. Espresso powder is commonly used in recipes that call for espresso, such as lattes, cappuccinos, and Americanos. To make a drink using espresso powder, water is heated to create steam, which is then forced through the ground coffee at high pressure. This results in a concentrated, rich flavor that is characteristic of espresso.
