To get a taste of summer sweetness in the middle of winter, freeze some of your corn. First, blanch the ears by boiling them for 3 to 4 minutes. Plunge the blanched ears into cold water. After the ears have cooled, scrape the kernels off the cob. Put meal-size portions of the cut kernels into plastic freezer bags. You can eat the corn lightly steamed, right out of the freezer (don't defrost it before cooking it). If you prefer your winter corn on the cob, blanch the fresh ears for 6 minutes, then freeze the whole ears. When you're ready to serve them, just steam the frozen ears for another 6 minutes.
