Roast peanuts at a lower temperature for a more complex flavour

Online instructions say that peanuts which aren't in a shell should be roasted for 15 to 20 minutes at 350°F, corresponding to 177°C. That can give good results, but roasting at 150°C (302°F) for 25 minutes is better. The lower temperature retains more of the raw peanut flavour while removing the "green" aspect of raw peanut flavour. It also creates plenty of roasted peanut flavour. The result has the best of both the raw and roasted peanut flavours. The lower temperature also doesn't burn the thin red peanut skins, so they don't become bitter like at 350°F. In either case, peanuts should be one layer deep, and they need to be stirred a few times while they're roasting. Fresh roasted peanuts taste noticeably better than commercially roasted peanuts.
