Why do bagels stay hotter than bread out of the toaster?

Bagels tend to stay hotter than regular bread after toasting due to their denser structure and lower moisture content. The denser dough retains heat more effectively, while the firmer crust minimizes heat loss. Additionally, bagels are typically boiled before baking, which can create a unique texture that helps insulate heat. This combination allows bagels to maintain their warmth longer than softer bread varieties.
