Which of the following is NOT one of the three purposes of a recipe card?

The purpose of a recipe card primarily revolves around guiding the preparation and presentation of food in a consistent manner. Among the options presented, providing nutrition information is generally not considered one of the core functions of a recipe card. Instead, recipe cards are meant to ensure meal consistency, supply detailed instructions for food preparation, and accurately price items for budgeting and inventory management. These components are essential for training staff in food preparation and ensuring that dishes meet set standards across different servings. Therefore, while nutrition information is important in food service, it is not a primary purpose of a recipe card, making it the correct choice in this context.
