I want to use the crafting method for other items. Just wondering if there was a string I could use. Thanks in advance.

Anything in regards to MineTweaker is handled in AbyssalCraft Integration.
In regards to ModTweaker, it's more that ModTweaker adds support for you, rather than you add support for it (as it's a MineTweaker addon for supporting other means of crafting added by mods through ZenScript).
