You do "evaporate water into salt".

but what if you could put salt into a placed filled cauldron of potion, then evaporate a the potion placed in a cauldron to get the salts returned with enchanting glint which has the potion effect spread between x how many salts required to salt it in the first place.

Salting foods with it will then put a shorter duration version of the potion in the food. like maybe a third as effective or something while still providing the increased saturating effects.

Next suggestion. You know how flowers are used in suspicious soups and they give additional potion effects to the soup thats hidden? what if you could mortar and pestle down the flowers which give those effects to produce "seasoning" which can be used to make seasoning mixtures with similar properties to the potion salts. Said seasonings also being able to have salt in said combinations.

Interesting suggestions, but they are a bit outside of the scope of this mod. I've made it to be a small mod for the modpack I wanted to make (which I still haven't got around to do).
I'll note this. maybe in the future this ideas can be implemented in some mod.

Alrighty, thats all I could hope for really, that you'd consider it. Didn't think it'd go in this mod, but in another food seasoning related mod if you ever want to expand the system.

it appears there is a mod called "spice shelf (api)" which is actually adding this idea via datapacks... Hmm... cross compat/integration time?
