Every ingredient carries a humoral nature, such as hot, cold, moist or dry, and each dish is built to push the eater's temperament back toward balance. Cooling agents like vinegar, sour fruit and gourd offset heating ones like honey, mutton fat and warm spices, so a recipe works as a dietary prescription as well as a flavor combination. This makes the cook a practitioner of preventive medicine working alongside the physician.
Many dishes are credited to named caliphs and princes, such as Ibrahim ibn al-Mahdi, and are accompanied by poems praising them. This shows that at the Abbasid court, inventing and describing food was an elite accomplishment practiced alongside poetry and conversation, not only a servant's trade. A recipe therefore carried status and authorship, and could be performed and circulated much like a verse.
The book treats good food as depending on the cook's character and habits as much as on the recipe. It extends this discipline to the diner, with rules for table manners, washing hands after eating, toothpicks and digestives, framing the meal as a regulated social and bodily ritual.
