[1.16.5] Recipe from .getRecipeFor() returns null when extending AbstractFurnaceTileEntity

[UselessRobot]

I've been trying to make a tile entity that extends AbstractFurnaceTileEntity but have run into a bump with getting the recipe from the smelting recipetype. I've had a look at some older posts about getting recipes from existing recipetypes but I can't quite make out what I'm missing. I've been able to narrow down my issue to my "implementation" of burn below:

Spoiler

	protected boolean canBurn(@Nullable IRecipe<?> recipe) {
		if(recipe == null) {
			TileEntityOnly.LOGGER.info("recipe is null.");
			
		}
		if (!itemHandler.getStackInSlot(0).isEmpty() && recipe != null) {
			//recipes are null fix this part
			ItemStack resultStack = ((IRecipe<ISidedInventory>) recipe).assemble(this);

			if (resultStack.isEmpty()) {
				return false;
			} else {
				ItemStack outputStack = itemHandler.getStackInSlot(2);
				if (outputStack.isEmpty()) {
					return true;
				} else if (!outputStack.sameItem(resultStack)) {
					return false;
				} else if (
						outputStack.getCount() + resultStack.getCount() <= this.getMaxStackSize() && 
						outputStack.getCount() + resultStack.getCount() <= outputStack.getMaxStackSize()
						) { // Forge fix: make furnace respect stack sizes in furnace recipes
					return true;
				} else {
					return outputStack.getCount() + resultStack.getCount() <= resultStack.getMaxStackSize(); // Forge fix: make furnace respect stack sizes in furnace recipes
				}
			}
		} else {
			return false;
		}
	}

 

Any help would be appreciated.

That's something big I missed. Considering the purpose of this mod I think it'd be better for me to not use AbstractFurnaceTileEntity and instead extend TileEntity and just use the smelting RecipeType.

Thanks for the help

EDIT:

After a closer look, RecipeTypes is also based on IInventory so it'd be more convenient to extend AbstractFurnaceTileEntity anyway. Though the main reason I had done this was that I was unable to get the burnProgress and litTime from AbstractFurnaceTileEntity. Is there anything stopping me from sending this information to my block's Screen?
