I just ate a protein bar with roasted coffee beans in it. I get that it is a good energy source and it tastes like coffee but is the coffee beans prepared in a certain way. I'm not quite sure if they are edible raw or what the beans have to go through. So how does raw coffee beans become edible coffee beans that can be put into all sorts of foods? Or are coffee beans left raw or even both? Please use reliable sources and all help is appreciated!
