What does it take to hit the spot?. Let’s investigate this from molecules to gastronomy, flavors, cuisines, tribes, experience. One should observe that “preparation” of the ingredients is ommitted. But its here precisely where we quite literally “draw blood” 🩸. Modern societies are mostly removed from this business, but a few engaged activists may find it disturbing and turn vegetarean. This is a misunderstanding of human history, society, and its underbelly#
