The recipe should use the ore dictionary.

Ah right, we have "stock" oredict names for those things now. I believe when I started the mod, they weren't there yet, but yes, good idea.

Note that I will not be able to get to this immediately, so you can use CraftTweaker to manually add a recipe using oredict.

I'll just make a pull request. I was too tired to do it last night.
