Drying seeds and roasting seeds are two different processes. To dry, carefully wash pumpkin seeds to remove the clinging fibrous pumpkin tissue. Pumpkin seeds can be dried in the sun, in a dehydrator at 115-120ºF for 1 to 2 hours, or in an oven on warm for 3 to 4 hours. Stir them frequently to avoid scorching.
To roast, take dried pumpkin seeds, toss with oil and/or salt and roast in a preheated oven at 250ºF for 10 to 15 minutes.
