How to create an item that is not consumed in crafting

[TyrrIsNear]

I've been trying to figure out how to make an item receive damage when used in a crafting recipe, but I'm not sure what the return for the getContainerItem method needs to be.

public class GrindingPot extends Item {
    public GrindingPot(Properties p_i48487_1_) {
        super(p_i48487_1_);
    }


    @Override
    public ItemStack getContainerItem(ItemStack itemStack) {
        damageItem(itemStack,1, this);
        return ItemStack.EMPTY.getStack();
    }

    private void damageItem(ItemStack itemStack, int i, GrindingPot grindingPot) {
    }

}

This is what my latest attempt looks like, any hints would be greatly appreciated

I forgot to mention, this is version 1.16.5
