Help needed with fuel item

I've been trying to make an infinite fuel item by returning said item after it has been used as fuel the same way a Lava Bucket returns an empty Bucket after it has been used. I am aware of the methods getContainerItem, hasContainerItem and hasCraftingRemainingItem but I don't know which one to use (if it even is one of them) nor do I know how they work. Can anyone help me get this to work?

Below is the items current code.

package com.hivemind.superheated.item;

import net.minecraft.world.item.Item;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.item.crafting.RecipeType;

public class BlazingCore extends Item {

	public BlazingCore(Properties properties) {
		super(properties);
	}
	
	@Override
	public int getBurnTime(ItemStack itemStack, RecipeType<?> recipeType) {
		return 400;
	}
}
