The Blueprint has a Required String parameter called “Category”. This String allows you to “Categorise” your recipes to a specific Blueprint Category.

If this string returns a Category not already existing it’ll create that Category and an appropriate Blueprint. If it finds an existing Category it’ll add the recipe to said Category.
