Nuts are soft when they are wet. You can spread the food evenly on a flat-bottomed plate and spread it into an O-shape, which is empty. Then turn to medium heat 1 min, and then put it in it for a little half a minute to 1 min before taking it out. Let it cool and see if it is not soft. If it's still a little damp, you can turn it over medium heat for a while. If the nuts are small, use a small fire, or you can reduce the time of watching them.
