The Blueprint crafting package can be used to add/remove recipes to/from the Immersive Engineering Blueprint crafting.

The Category String is quite special. For any string entered that doesn't already have an established Category, it'll create a new Category and thus a new Blueprint. This means that you could add a Blueprint Category called "Banana Pancakes" that provides "Food Recipes". After the first entry found it'll generate all additional recipes for that Category String under the generated Category.

You can call the Blueprint package using mods.immersiveengineering.Blueprint.
