How long does the corn cook until fully cooked after the water boils

After the water boils, corn can generally be cooked thoroughly for 15-20 minutes, depending on factors such as corn variety, maturity, and heat intensity. The cooking time of corn mainly depends on its starch content and texture. Fresh sweet corn has sufficient moisture and low starch content. Usually, it can be fully cooked after boiling for about 15 minutes, with a fresh, tender and juicy taste. Old corn or glutinous corn has a higher starch content and a denser texture, which may take up to 20 minutes to ensure complete ripening. During the cooking process, you can use chopsticks to lightly poke the corn kernels to test their ripeness. If they can easily penetrate without any raw starch taste, it means they are ripe.

In special circumstances, the cooking time needs to be adjusted. Frozen corn does not require thawing and can be cooked directly, but the low temperature will prolong the heating time. It is recommended to add about 5 minutes. If cooked in a pressure cooker, the same degree of maturity can be achieved in 8-10 minutes after SAIC cooking. Boiling with bracts can preserve more flavor, but the outer leaves may hinder heat conduction and need to be extended for 3-5 minutes as appropriate. The heat transfer in the central part of varieties with thicker corn cobs is slower, and it can be boiled in half vertically to shorten the cooking time.

When cooking corn, it is recommended to keep the water completely submerged and avoid frequent opening of the lid halfway. Adding a small amount of salt can enhance sweetness, but alkaline substances can damage the vitamin B complex. Take it out immediately after cooking to prevent excessive water absorption from affecting the taste. diabetes patients should pay attention to controlling the consumption. Those with weak gastrointestinal function can appropriately extend the cooking time to make starch more digestible.
