Spent coffee grounds can be used as food ingredients in order to add new textures and flavors to dishes, while also contributing to waste reduction by using a byproduct of coffee consumption; in fact, depending on how the coffee was brewed and on which type of beans have been selected, the coffee grounds can give a soft coffee flavor to dishes and also a crunchy texture when used in baked goods like brownies or cookies.
Moreover, coffee grounds contain small amounts of nutrients, including potassium and magnesium and they can therefore contribute, even if just a little, to the overall nutritional profile of the food they are used in.
