I haven't found another topic that stated this, so I shall state it:
My idea is that every recipe (ingredients and all) appear in the encyclopedia.
My thought is that one would just click on the name of the food/booze and it would open the ingredients list for the item:)
+1 if you like it! Feel free to add/remove as this topic expands (if it does)!
EDIT: If there is another topic that covers this, please leave the link to it, I am sorry if there is!
