Culinary Agent

A Culinary Agent is a general term for any alchemical substance which enables an alchemist to turn most materials into a specific item of food, as long as they have one such food item with them.
Most Culinary Agents are edible themselves and tend to change the target item into a food similar to themselves. Most types of honey produces sweets while the root of a Bittergras tends to turn things into a bitter and poreous mass - often with interesting healing qualities.
