Was harvesting sweet corn yesterday and prepping for vacuum sealing and freezing. Blanched the ears for 9 minutes, let dry, and then sealed four cobs to a bag. Had a few ears of corn in the freezer last winter. Wife liked it so much she requested two ears for herself per meal instead of the typical one. So far 16 bags in the freezer.
We found the best way to warm the ears of corn was in the oven. Let the ears thaw in the bag. Warm in a 250°F oven on a rack until the internal temperature of the cob reached 90°F.
