Less than 1% of all of the corn grown in Iowa each year is sweet corn, this is equivalent to about 3,400 acres. Sweet corn is a good source of vitamin A, C, and soluble fiber. Another fun fact is that a corn cob always has an even number of rows.
Look for silks that are brown and dry at the ear tip. Fresh green hucks should be tightly wrapped around well filled in ears with bright colored, plump, milky kernels. Avoid ears with insect or disease damage.
Unhusked sweet corn can be stored in the refrigerator at 32°F for 4-8 days.
