"A sort of Bread, of which a Mouthful can maintain a Man eight daies, without eating any thing else. Take a quantity of Snails, and make them void their sliminess; then dry and reduce them to fine Powder, of which make a Loaf, with a Mouthful of which a Man may be eight days without eating."
Nicolas Lémery, Modern Curiosities of Art & Nature (1685)One bite of this special bread and the idea of eating anything at all will nauseate you for eight days! The only problem: to learn how to make snails void their sliminess, you'll have to consult a different manual.
