Which cooking method uses both conduction and convection?

The cooking method that utilizes both conduction and convection is braising. This technique involves cooking food slowly in a small amount of liquid after first searing it at a high temperature.

During the initial stage, conduction occurs as the hot surface of the pan transfers heat directly to the food. This process is key for developing flavor through browning while creating a crust on the surface. Following this, the liquid is added, and the dish is covered and cooked at a lower temperature. In this phase, convection comes into play as the heat from the liquid circulates around the food, ensuring that it cooks evenly and absorbs the flavors of the braising liquid.

In contrast, methods like frying primarily rely on conduction through contact with hot oil, baking mainly uses convection within an oven without much direct contact heat, and boiling predominantly involves convection in the water but has limited conduction since the food is submerged. Therefore, braising uniquely combines both cooking methods, making it the correct answer.
