Boiling time for corn varies depending on its freshness, size, type, and whether it’s husked or not. Fresh, sweet corn generally needs to boil for 2-10 minutes. If the corn is fresh and sweet, it will take less time, around 2-5 minutes if husked, and about 10 minutes if unhusked. Frozen corn takes longer, with shucked kernels needing 2-3 minutes and frozen cobs requiring 5-8 minutes. Avoid adding salt to the boiling water as it can harden the kernels. For the best taste, choose fresh corn from local markets during the peak season.
