curently on version Aquaculture-1.21.1-2.7.14 for NeoForge

tried disabling fish fillet recipes through kubejs, datapacks, even deleted the fish fillet recipe from the jar and it still persists

is it hardcoded, a bug, or is there a way to actual get rid of the recipe? or maybe i'm just dumb and modified the wrong files

I know it's possible with KubeJS for sure, a guy in a Discord server (In the Aquaculture channel) managed to do it a while back.
I'm personally not familiar with KubeJS - this is what the guy said, when he figured it out. Might be useful to you hopefully!
