You're saying that, knowing what the ingredients for duck confit were beforehand, you were able in 3 clicks to make this app say what the ingredients for duck confit were.

A better test (I make a lot of duck confit): do you know how to make duck confit now? Did you learn from this app? What are roughly the steps you learned?

Well, what I'm saying is that, knowing roughly how to make duck confit but being unsure of the proportions, I was able to find out what I needed to know easily. You, on the other hand, weren't able to find out something you already knew; that doesn't sound like a problem to me. If you know exactly how to make something (or you don't know at all how to make something at all) then your right, don't bother using this app.

A good test for an app that is designed to teach you how to make a dish is: do you know how to make it now? But that's a bad test for this app, which helps you build recipes that you already know something about.

I had the other impression about the app; that it was intended to tell you what you needed to make for a dish you didn't know how to make (because if you did, you wouldn't need the app to tell you what you needed).
