toast means: Most often, browning is done using dry heat sources such as an oven or toaster. Many recipes require that you toast seeds, nuts and spices to give them flavor. These can be baked in an oven, or in a pan with oil. Stir or toss the seeds or nuts often until they are nicely brown, but not burnt. (in Cooking Dictionary)
