Roasting

For thoughtful child sponsors
Roasting is cooking with dry heat, whether an open flame, oven, or other heat source. Roasting usually causes caramelization of the surface of the food, which is considered a flavor enhancement. Meats and most root and bulb vegetables can be roasted.

The only difference between baking and roasting is that baking excludes open flame.
