Ingredients are badly coded in this game. There is no way to program them to check whether a player has the pack installed that they came with. That is why you won't find recipes calling specifically for peas, avocado or bell pepper. It would make the recipe unusable for players who do not have the respective pack.
It's also the main reason I had to get rid of my moreingredientsrequired mod after CoL released.
I really wish they would add more code to check whether a certain EP is installed. They were one of the strenght's of TS2 programming.
