I was just wondering, if the file does not get picked up at all by the engine if another mod is used as well or if one in a .pak file from the documents folder is enabled.
Maybe the game ignores everything in the Main and Shared folders if another mod - a 'new style' mod - is used together with one of the 'old style' ones like Scales and the crafting extension.
Try disabling all mods in the game's mod menu and test if the recipes work without any other mods enabled.
