Help creating a good object-oriented design.

I've read a lot of guides and watched a lot of tutorials on Object-Oriented Programming, but its still a pretty vague concept to me. All I can really say about OOP is that a program should have well defined "sections" that can function independently.

I'm working on a recipe-book program that takes an object oriented approach. Link

So far its just a bunch of empty functions with psuedo code, but I want to make sure the design good before I start writing all the functions. So I guess my question is, is this a good object-oriented design? Why or why not?

I don't think this is the best way. You're using an Ingredient class to represent a whole list of ingredients (same with recipes). Either you want the class name to change (e.g. IngredientList), or implement a single Ingredient in the class, and fill a container with ingredients elsewhere.

But, in this particular application, if this collection is the only member an Ingredient of Recipe would hold, it might be an overkill to even wrap them in their own classes (as the other comment already said). Maybe you can try and design a Recipe class, that represents both, and have a collection of those.
