Only in 1981 the precious Codex Romanoff was discovered. This was where Leonardo used to take note of these recipes and thoughts on cookery and etiquette. The codex also shows diverse projects for machines, designed by Leonardo himself, as aids in kitchen work. These are absolutely amazing gadgets. From the spaghetti stretcher to the pepper grinder inspired by the Sforza tower, this manuscript is an amazing source, not only for the cooking tradition of the Italian 16th century, but also a mirror which reflects another facet of his genius!
