2. Wash the bought yam, cut it into small pieces, then wrap it in tin foil, put it in a frying pan or microwave oven, turn on the power and set the temperature and time, so that when the time comes, you can take it out, remove the tin foil and bake the yam.
3. It should also be noted that yam is hard when it is not ripe. We'd better stick chopsticks on it a few times during baking. If it can penetrate, it means it is ripe. If it is not penetrated, continue to bake until it is completely cooked.
