I have been growing and freezing sweet corn for years and when they are ready to pick I freeze as soon as possible. I take off the outer leaves and tassels and pack singly in plastic bags, seal and freeze straight away with no blanching. To cook get a pan of water boiling and then put the cob in still frozen and cook for 10 minutes. To tell if a cob is ready for picking stick a finger nail into a nib and if the liquid comes out milky it is ready to pick, if the liquid is clear leave for a day or two and test again.
