Cooking System Help

So i have this cooking system with an array called
cookingList that has a size of 3.
Depending on what is in the list dictates the result item
so for example if the list contains an apple, a carrot, and a cabbage, the result will be a vegetable soup.
I would like to know a good system that searching through a list of recipes and how to define that recipe.
Right now my method would be to do a series of if statements like
if(cookinglist contains x, y, z)
{
add item c
}
Though i feel as if this would be quite inefficient and provides a poor workflow

To answer the question, yes this is a direct application of something called a Graph Database and an exact example is outlined in this article. But, depending on your experience with these sorts of databases, development might be a bit clumsy at first.

With that said, there’s a line between healthy inquiry into possibilities and premature optimization that bogs down your development pipeline. You’re right that for a “large” number of potential recipes, this might be a bit slow to use a naive lookup with one ingredient at a time. But, you might want to go ahead and implement this naive format wrapped in a manager / “store” class to get started. Something like:

public class RecipeStore
{
    // constructor

    public Recipe[] GetRecipes(params Ingredient[] ingredients)
    {
        // Whatever you'd use to get possible dishes
    }
}

This way you can get started and see this working, rather than get slowed down by the details of nodes, edges, and queries. Then later (once your performance starts to suffer from the number of recipes to sort through), you can start to implement a more optimized method into your GetRecipes calls.
