The ideal boiling time for corn depends on its freshness, whether it is husked or unhusked, and if it is fresh or frozen:

• Fresh, unhusked corn: Boil for about 10 minutes. The husk protects the kernels, so it takes longer to cook

• Fresh, husked corn: Boil for 2 to 5 minutes, with the freshest and sweetest corn needing only about 2 minutes

• Frozen corn on the cob: Boil for 5 to 8 minutes until tender

• Frozen shucked corn kernels: Boil for 2 to 3 minutes

Some alternative methods suggest adding corn to boiling water, then turning off the heat and letting it sit covered for 10 minutes or more, which yields tender corn without risk of overcooking

. Boiling corn for longer than 5 minutes can cause the kernels to shrivel and become mushy, reducing sweetness and texture quality

. In summary, for fresh husked corn, boiling for 2 to 5 minutes is sufficient, while unhusked corn or frozen corn requires about 10 minutes or less depending on the type. Avoid over-boiling to maintain the best flavor and texture
