Fiorauanti Bolognese, Leornardo: Del Compendio de i Secreti dell'Eccell. Medico, & Cirugico M. Leonardo Fiorauanti Bolognese, Libri Cinque. (Vincenzo Valgrisi, Venice, 1554)
This is actually a "book of secrets", and contains recipes and treatments for the physician and surgeon, as well as alchemical recipes and beauty treatments - and some food-related recipes and information. I love the overall eclectic nature of the work, and also, specifically, the fact that he includes candy recipes.
