Try using the command "/cr check" and if that works then try the find again.

There appears to be some problem with your CookingRef_User file.
If the preceding doesn't work, rename the file <Lotro dir>/PluginData/<account>/<server>/AllCharacters/CookingRef_User.plugindata and then log into your character and see if you get an error. This file keeps track of your known recipes and will be recreated if it is not found.

My level 150 cook finally achieved Apprentice standing with the Umbari Cook's Guild, so I can now add most of the remaining Umbari recipes. I only lack the 3 Fortifying recipes which require Journeyman standing (and it will be a while before I achieve that).
