I admit that after spending 16 years as a Research Chemist and using some pretty sophisticated instruments, measurements and calculations, my "bushel" of corn, as we euphemistically call it means very little. What you get is two of the large brown grocery sacks, full of fresh out-of-the-field still in the shucks corn-on-the-cob. Experience tells me the size, maturity and quality will vary from ear-to-ear and from sack-to-sack and from sacker-to-sacker. What with paying $15 per "bushel", what ever that turns out to be, waiting in line for 3 hours, driving 40 miles each way, spending the rest of the day cleaning, blanching and freezing the corn, exact measurements and price come secondary to the fact that really good corn is best fresh picked and immediately frozen.
I am told that as soon as the corn is picked, it activates an enzyme that begins converting the sugar in the corn to starch, thus reducing the quality and flavor very quickly. Blanching and freezing kills the enzyme and halts the process. The whole family loves this fresh-frozen corn, and it sure tastes great around New Years. It is probably the only thing in the world I would "willingly" wait in line that long for.
