An espresso puck is the compressed coffee grounds that are left in the portafilter after brewing espresso. You can use it to enhance the flavor of your coffee or to create unique culinary treats. It adds a rich, bold flavor to sauces, soups, and desserts. Additionally, It can be used as a natural exfoliant in homemade beauty products.
The flavor of the espresso puck depends on the type of coffee beans used, the roast level, and the brewing method. Darker roasts and finer grinds will produce a more intense flavor. Experiment with different types of beans and brewing methods to find the combination you enjoy the most.
