I'm working on a mod to (lightly) overhaul the brewing system by separating potions into categories with different potion bases (water+nether wart for "awkward" negative potions, honey+glowstone for "thick" positive potions).
I'm currently following a tutorial by Kaupenjoe, which shows a rather easy way to add potion recipes for custom potions, however what I'm wondering right now is if there's any way to completely disable vanilla recipes so that players can't get potions in unintended ways.
