1, the cooking time of corn is not fixed. If it is ordinary corn or fresh corn, it will be cooked in about 10- 15 minutes, but if it is waxy corn or old corn, the cooking time will be longer, and it will take 15-20 minutes to finish.

2. If ordinary corn and waxy corn are cooked in the same pot, their maturity time is different, so it is necessary to pick up the corn with a short time first, and then continue to cook the corn with a long time, and after cooking, it cannot be soaked in water for a long time, otherwise it will lead to nutrient loss.
