Final answer:
All elements such as cooking procedures, portion size, and amount of each ingredient are part of a standardized recipe for consistency and accuracy, similar to how chemists need precise measurements for their experiments. So, the option is D.
Step-by-step explanation:
The inclusion of cooking procedures, portion size, and the amount of each ingredient is essential in a standardized recipe. Unlike the imprecise methods of the past, where cooks would estimate the amounts needed, in a standardized recipe detailed information is provided for each of these categories to ensure consistency and accuracy in the preparation of the dish. Just like chemists who require precise measurements for their experiments, cooking with a standardized recipe enhances the reliability of the resulting food in terms of texture, taste, and appearance.
Therefore, D is the correct option.
