What does the culinary term 'brulee' refer to?

The term 'brulee' specifically refers to a culinary technique involving caramelization, which is most commonly associated with creating a dessert like crème brûlée. This process involves sprinkling a layer of sugar on top of a dish and applying heat from a broiler or a torch until the sugar melts and caramelizes, resulting in a dark, glossy crust with a rich, deep flavor.

This method not only enhances taste but also adds textural contrast to the smooth custard beneath. The term itself is derived from the French word 'brûler,' meaning 'to burn,' which perfectly describes the controlled burning or caramelizing of the sugar. Therefore, the correct answer is related to the dark flavor and caramelizing technique that defines the essence of 'brulee.'
