1.16.4-1.13.4
Most infuser recipes are named after their input items, e.g. aquamarine.json or crystal_sword.json.
However, two recipes (gunpowder.json and grass_block.json) are named after their output items.
This is a minor inconsistency, but should probably still be fixed, as it could cause confusion for those creating infusion recipes for gunpowder or grass blocks.
