Uh, exactly. See how you describe the same concept:

> A recipe is an ordered list of steps of what to do

Understandable.

> a list can be used for a recipe

Not so much.

Moreover, a recipe usually at least consists of two parts, ingredients and steps.

"pierogi_recipe": { ingredients: Set<(Item, Quantity)>, steps: List<Step> }

So the analogy kinda muddies the waters.
