One other way of saying “melt that horse” is “cook that horse.”
I forget the exact recipe for hide glue, but I think it mostly is a process that involves soaking and heating hide with lime (not the fruit). Also materials that can be used in the production of leather.
Anyways, if you cook enough horse and you make enough horse leather in an area with lime, and you’re observant enough, hide glue is sort of an inevitable discovery.

Which means there’s a decent chance that someone ate glue before anyone used it to stick things together.
Maybe multiple people if it went like this:
A: I’m going to try this eats spoonfull
B: How is it?
A: Mmmm…!?
B: Oh he likes it, I’ll try some, too!
C: Do you agree with A?
B: Mmmm…!?
A: Mmmm! Mmmmm!
D: Wow they really like it! Ok, everyone grab a spoon!
“There’s more than one way to melt this horse” is totally an idiom in the glue industry I promise.
