"Set" is the word in the English language with the most definitions, and it adds confusion to dialogue when one word has too many definitions. I propose taking a specific definition from set and giving it its own word, "truft". The specific definition that would be taken from "set" is "harden into a solid or semisolid state." and will here on be defined as "truft".

e.g. As the gelatinous mixture cools, it trufts.
