Generally, corn can be cooked for about 15-20 minutes and white sticky corn can be cooked in cold water for 25 minutes. Boil the fruit corn and cook it in cold water for 15 minutes. Boil fresh corn and cook in cold water for 20 minutes. Corn is usually cooked in cold water, hot water is not recommended. Here is how to cook jade based on my years of life experience.1. Boil fresh corn and put it into cold water for 20 minutes. The cooking time is shorter because the fresh corn itself is more watery. To ensure thorough cooking, it is recommended to cook it in cold water for 20 minutes.2. Boil fruit corn and put it in cold water for 15 minutes. Because fruit corn is usually small and high in sugar content, it is easy to cook. Usually 15 minutes in cold water is enough. 3. Boil white glutinous corn and put it into cold water for 25 minutes. Due to its high starch content, white glutinous corn is difficult to cook. It is recommended to cook it for at least 25 minutes before eating. 4. Cook it in a rice cooker, minus about 5 minutes for each of the above bases. Because the rice cooker itself has high pressure, the cooking time can be reduced by 5 minutes. 5. Cook in pressure cooker. The above bases can be reduced by 10 minutes. Because the pressure cooker has a lot of pressure, the heating is also very fast and stable. Usually corn can be cooked in 6 minutes. Do you cook corn in cold or hot water? Corn is usually cooked in cold water and hot water is not recommended. The reasons are as follows:1. Cooking corn in cold water cooks it thoroughly. Because the corn cooked in cold water is slowly heated, and the corn itself is high in starch, it is slowly heated, so the corn cooked in cold water can be cooked through better, while the corn cooked in hot water is heated first on the outside, so the inside is more difficult to cook, and is not as thorough as cooked in cold water; 2. The corn cooked in cold water tastes soft and sticky. Because corn cooked in cold water can be cooked through the corn, the inside and outside of the corn can be heated together, so corn cooked in cold water will taste softer and more glutinous, while the inside of hot water because the outer layer is heated, the inside can no longer be easily heated, so it is difficult to cook, and the taste is harder. Corn is sweetest when cooked for a few minutes. Cooking corn is recommended to add the following two points to the above mentioned cooking time can make the corn sweeter:1. Use two layers of skin and beard to cook corn together. To cook corn to a sweeter, more flavorful consistency, do not completely remove the skin and husk from the cooked corn. Simply peel a few thick layers of skin on the outside, leaving two layers of skin to cook with all the corn husks inside. The corn will keep its sweetness and taste sweeter and more delicious.2. Add a tablespoon of salt while cooking the corn. Adding a spoonful of salt to the water when boiling corn can increase the electrolytes in the water, which will help stabilize the corn with heat, and the corn will be sweeter and more delicious because of the salt, which is two birds with one stone.

(3) When cooking corn, you can also add half a cup of milk in the rice cooker, so that the cooked corn tastes more fragrant.
