1. When cooking old corn, peel off all the skins, then wash them with clear water, put some chopsticks in the pot, put the old corn and chopsticks in the wrong place, put them in clear water, and then cook them with fire. If the old corn is big, you can also stick a few holes in the middle with chopsticks. After boiling, turn to medium heat and cook for 30 minutes.

Before cooking, put the basket in the pressure cooker at the bottom of the pot and add water, put the old corn in it and add appropriate amount of water. After high pressure comes up, turn to low heat and cook for 15 minutes. Then let the air valve descend by itself, and take out the old corn and eat it. The old corn cooked in this way is soft and rotten, which is suitable for the elderly.

This method is to peel the old corn, put it in a pot, add three to five grams of alkaline flour, then start cooking, boil it with high fire, and turn off the fire about 20 minutes after the heat is adjusted to medium. When it is taken out, most of the old corn is in a flowering state and can be eaten directly.
