Espresso
Description
Espresso is a concentrated form of coffee that is typically made by forcing hot water under pressure through finely-ground coffee beans. This process results in a thicker, more potent beverage with a higher concentration of suspended and dissolved solids compared to regular coffee. Espresso is known for its rich flavor, creamy consistency, and a layer of crema on top— a frothy emulsion of coffee oils and brewed coffee. In the culinary world, espresso is not only savored as a standalone beverage but also used as a key ingredient in a variety of recipes to impart a deep, robust coffee flavor.
Common uses
Espresso is commonly used as a base for other coffee drinks, enjoyed on its own as a quick caffeine fix, or incorporated into desserts and savory dishes. Its robust flavor makes it a popular choice for adding a rich coffee essence to cakes, ice creams, sauces, and marinades.
