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.
