This includes all recipes from the Equipment and Alchemy & Food tabs of your crafting menu.You can gain recipes via various methods (finding, buying, quest reward) and often you can find one and the same recipe several times.If you try to learn a recipe you already know, the game will tell you so and prevent you from wasting it.
Credit for the detailed information goes to Lucki88 :
To make sure you get this you need to buy all the recipes from Mama Hooqua in the swamp as soon as you meet her and as you're nearing the endgame, keep a save file from somewhere in Thorniara(up to the moment shortly before entering Xardas' tower).
That's because once you get to the final battle, revisiting all areas before the Sea Cliff Monastery will be impossible, but as long as you're still in Thorniara you can backtrack all the way to where you got off the boat with Diego and check with all merchants if they have any recipes you're still missing.
