Ok since I am new to modding I will take your advice and avoid that for now, but would creating the new item interfere with recipes (I would prefer to keep the same vanilla recipe) and I would also prefer to not see two pumpkin pies in the creativetab. Also would it be any easier to replace the vanilla Item if I searched through the source code of an already built mod that does this. For instance Thaumcraft 4 replaces the bedrock with it's own code.
