I've managed to remove the vanilla recipe for the torch

public static void TorchesPerCoal(RegistryEvent.Register<IRecipe> event){
	ResourceLocation torch = new ResourceLocation("minecraft:torch");
	IForgeRegistryModifiable modRegistry = (IForgeRegistryModifiable) event.getRegistry();
	modRegistry.remove(torch);
}

But how to properly re-add the recipe since is configurable via Config?

Could you clarify what you mean by this?

 

Do you mean that the replacement recipe is only enabled if a config option is set? If so, you can create an IConditionFactory that returns the value of the config option and use the condition in your recipe.

 

diesieben07 explains this in more detail here:

 

Edit: IConditionFactory, not IRecipeCondition.

I have set in the config the number of torches a crafting gives and I need to change it.

Ok seems like that even removing the recipe doesn't work
It doesn't enter into the event (RegistryEvent.Register<IRecipe> or <Potion>)

Did you mark your event with the correct annotation?

I might be wrong but isn't @SubscribeEvent the annotation for every event?

Just use your json files.

This is the Events Class

package net.insane96mcp.iguanatweaks.events;

import net.insane96mcp.iguanatweaks.IguanaTweaks;
import net.insane96mcp.iguanatweaks.modules.ModuleGeneral;
import net.minecraft.item.crafting.IRecipe;
import net.minecraft.potion.Potion;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class RegistryRegister {
	
	@SubscribeEvent
	public static void EventRegisterIRecipe(RegistryEvent.Register<IRecipe> event) {
		IguanaTweaks.logger.info("RegisteringRecipes");
		ModuleGeneral.TorchesPerCoal(event);
	}
	
	@SubscribeEvent
	public static void EventRegisterPotion(RegistryEvent.Register<Potion> event) {
		IguanaTweaks.logger.info("RegisteringPotions");
		ModuleGeneral.AlterPoison(event);
	}
}

And I register it with MinecraftForge.EVENT_BUS.register(RegistryRegister.class); in Proxy's Init();

Seems like that using @SubscribeEvent isn't enough.
I had to register the event class with @Mod.EventBusSubscriber(modid = MOD_ID)

 

Now back to the original question. 
How to dynamically register a recipe with variable output count?

You'll need your own IRecipeFactory implementation that creates a recipe of the appropriate type and uses the config option to determine the output item's count. You can see the IRecipeFactory implementations for the Vanilla and Forge recipe classes in CraftingHelper.init.

 

The IRecipeFactory class needs to be registered in the _factories.json file, just like IConditionFactory and IIngredientFactory.
