Storing extra data about an object

I want to store some extra data about an object (in this case, a recipe) without storing it in the object itself. What is the best way of doing this?

Here is a simple example. Am I doing something wrong architecturally?

var recipes = {
    scones: {egg:2, milk: 5},
    pancakes: {eggs:3, milk: 2}
}

var recipesCooked = {
    scones: 0,
    pancakes: 0
}

function makeRecipe(recipe){

  // I don't want to have to do this loop every time.
  // Is there a better way of storing this data??
  for(var key in recipes) {
    if(recipes.hasOwnProperty(key) && recipes[key] === recipe){
      recipesCooked[key]++;
    }
  }
  //...snipped...make the recipe
}

makeRecipe(recipes.pancakes);
//recipesCooked.pancakes should be 1

In other words: I need some way of tying the extra data (recipesCooked) to the correct recipe, and the only way I know of doing that is by using the same key. But this seems bad, especially because I have to iterate back through the recipes to find the name of the key.
