Does sponge save recipes on restart

Hello, I want to do a plugin which is creating recipes based on a GUI but I don’t know if Sponge is saving the recipes on reload/restart and I need this information speedily because I have to know if I have to do a recipe loader based on a .conf file or not.

Afaik, Sponge will not save any modifications made to a registry. Anyway, when you have a doubt, just test and see.
