Ok, now that I've gotten my brewing recipe to work I'm trying to actually create a new potion type. I've looked at some other forum threads. This looks like it should be correct but I can no longer brew the item. I can't find the new potion type in the menu so something is wrong:

@Mod.EventBusSubscriber(bus = Bus.MOD, modid = "wof")
public class ModPotions {

    public static final DeferredRegister<Potion> POTION_TYPES = DeferredRegister.create(ForgeRegistries.POTION_TYPES, WorldOfFood.MOD_ID);

    public static final RegistryObject<Potion> HOT_COCOA = POTION_TYPES.register("hot_cocoa", () -> new Potion(new EffectInstance(Effects.SATURATION, 3600)));

    @SubscribeEvent
    public static void registerPotions(FMLCommonSetupEvent event) {
        event.enqueueWork( ()->
            BrewingRecipeRegistry.addRecipe(Ingredient.of(Items.POTION), Ingredient.of(Items.COCOA_BEANS), PotionUtils.setPotion(new ItemStack(Items.POTION), HOT_COCOA.get()))
        );
    }
}

 

That fixed it, thanks! I'll work on changing my ModId. 🙂

I put this in my mod class constructor:

ModPotions.POTION_TYPES.register(FMLJavaModLoadingContext.get().getModEventBus());
