What does 'R' in the grading system for pizza quality refer to?

The 'R' in the grading system for pizza quality refers to the rim size of the crust. This grading criterion focuses on the physical characteristics of the pizza's crust, particularly how thick or thin the outer edge is. A well-defined rim can affect not only the aesthetics of the pizza but also its overall texture and taste experience.

Understanding this grading aspect is essential for maintaining consistency and ensuring customer satisfaction in pizza quality. A correctly sized rim can enhance the structural integrity of the pizza, providing a balanced bite and allowing for better holding of toppings and sauce.
