How long can corn kernels be cooked

Corn kernels are usually cooked for 8-10 minutes to fully ripen, and the specific time depends on factors such as corn kernel size, freshness, and firepower. The cooking time of corn kernels is closely related to their texture and moisture content. Fresh corn kernels, due to their sufficient moisture content, usually soften by boiling over low heat and continuing to cook for 5-8 minutes. Frozen corn kernels need to be thawed in advance or the cooking time extended by 2-3 minutes. Using a pressure cooker can shorten the cooking time to 3-5 minutes, but it is important to control the pressure to avoid overcooking. The standard for judging ripeness is that the color of the corn kernels becomes brighter, the volume slightly expands, and the elasticity can be felt by lightly poking with chopsticks. If making corn soup or complementary food, it can be extended to 12-15 minutes to make the texture softer and smoother. Old corn or dried corn kernels need to be soaked for 2 hours in advance, and it takes 15-20 minutes to soften after boiling. When cooking whole corn with a core, the innermost bracts should be retained and extended for more than 15 minutes. Special varieties such as purple corn are recommended to be cut open and boiled for 10-12 minutes due to their thick outer skin. When using thick bottomed containers such as cast iron pots, turning off the heat and letting it simmer for 3 minutes can reduce the occurrence of hard cores. If corn kernels still harden after cooking, it may be due to prolonged storage time causing starch aging. Adding a small amount of edible alkali can help soften them.

When boiling corn kernels, it is recommended to soak them in water for 10 minutes to remove impurities. Adding a little salt after the water boils can maintain sweetness. When cooking with diced carrots or green beans, the corn kernels should be boiled for 5 minutes before adding other ingredients. People with weak digestive function can extend the cooking time appropriately to make corn paste that is easier to absorb. The remaining cooked corn kernels need to be drained of water and stored in the refrigerator. It is recommended to consume them within 2 days to ensure taste.
