The in-game recipe list has a problem that really bugs me: it doesn't tell you what the recipe is good for. Sure, you can see that if you hover over the actual item, but if you already have it, you don't need to cook it. Frequently, I go there saying, "Okay, I need (for example) a speed increase..." and have to mouse over the items I have and see if any of them will do that for me. If I don't have one and I don't remember what it is, I'm hosed. So I went ahead and created a recipe index, which I hope others may find useful. Let me know if you find any mistakes. (EDITS: Added indicators for other effects, organized lists better, added Swordfish Steak)
