I need the relock ability for an tutorial. In this tutorial you craft an "Awakening Potion", but later on in the game, the "Awakening Potion" is called differently because they didn´t know the right name for it right away. Renaming a recipe should do the trick too.^^
To unlock the recipe by name gives the advantage to not mess up you recipe unlock books. In my game you can find recipes in bookshelfs, but when I mess around with the position of the recipes in the plugin, the index to unlock might change and cause maybe trouble.
Thank you for your quick reply as always.
