What is the purpose of cutting hot dogs in half before cooking?

Cutting hot dogs in half before cooking serves the primary purpose of enabling even cooking and caramelization. When hot dogs are cut, the increased surface area allows for better heat circulation during the cooking process. This leads to a more uniform temperature throughout the hot dog, ensuring that it cooks evenly, which can help prevent any undercooked sections. Additionally, the exposed edges of the cut surfaces are more prone to caramelization, enhancing the flavor and texture of the hot dog by creating a nice, crispy outer layer while keeping the inside juicy and tender.

The other options present various considerations, such as potentially reducing cooking time or improving presentation, but they do not directly address the critical aspect of achieving even cooking and optimal flavor development, which is best supported by cutting the hot dogs in half.
