Store-bought roasted peanuts work well here, but if you want to roast your own peanuts, heat oven to 250 degrees. Place raw nuts on an oven tray and roast for 15 to 20 minutes, until fragrant and very slightly golden. (Keep an eye on them, as they are easily burned.) Cool nuts on a plate, then rub nuts between your fingertips to loosen their skins. Shake nuts as you blow over them; skins will blow away.
