Which item requires the use of a stainless steel pan of a specific size for preparation?

The requirement for a stainless steel pan of a specific size for the preparation of hard-boiled eggs primarily relates to the consistency and quality of cooking these eggs. Using a designated size ensures that the eggs are submerged evenly in water, promoting uniform cooking and preventing issues such as cracking during the boiling process. Additionally, the specific size can help control the temperature and cooking time, which are crucial for achieving the desired doneness without overcooking.

In contrast, the preparation of grilled chicken, fried fish, and mashed potatoes does not typically necessitate the same level of precision in pan size as hard-boiled eggs. Grilled chicken and fried fish can be cooked with a wider variety of pans depending on the quantity and cooking method, and mashed potatoes are generally prepared using different types of equipment that focus more on mixing and mashing rather than specific pan dimensions.
