Coffee flour isn’t really a flour. And although it is from the coffee plant, it doesn’t taste or smell anything like the roasted coffee beans we know and love.
Coffee beans are actually seeds and, like many seeds, they grow inside a fruit. The fruit that surrounds a coffee bean is called a coffee cherry. After harvesting the coffee beans, the coffee cherry has traditionally been discarded. Billions of pounds of coffee fruit was simply discarded every year. But now this tasty part of the plant is being reclaimed as an edible crop. The cherries are dehydrated and ground into a fine powder and sold as coffee flour or coffee cherry flour. But it functions more like a spice or flavoring agent than a flour.
