Grow and Mill Your Own Corn

While sweet corn is the common choice for most gardeners (who doesn’t love its rich, milky flavor?!), there are other types of corn readily available, of which I knew very little until 2 years ago. Christmas 2015 I was given a jarful of heirloom corn seed by a friend, was told it was ‘grinding’ corn. I had never milled whole corn kernels, but as always, was happy to expand my learning! Later, I was informed that it was a Floriani Red Flint Corn.

You can read more about it in this Mother Earth News Article. Originally grown in Italy, it makes a light pink colored cornmeal or corn flour and is wonderful in all kinds of baked goods! When milled into flour, it acts as a quick gravy thickener. Always looking for healthier alternatives to potato starch and not liking the flavor of most flours, I fell for this natural, home-grown alternative!

Because I had found a suitable use for this corn that didn’t require planting an entire field to make it worthwhile, I just had to save some of the seeds! Into the soil they went that spring! Even though we had an exceptionally wet year, the corn did well and stalks averaged out at 7 ft in height.

I watered and watched their growth, was wondering about the outcome. Had I actually found something for my homemade gravies and stews? Or would the growing and cleaning process be too much? Being naive, I planted on single row  (see year-end garden picture below) thinking to get corn for milling and shade for my red rock cabbages! When harvest came, some cobs were lined with even, full rows of kernels. Others had gaps in the kernels and I wondered why? It was then that I remembered: if planting corn, there ought to be at least several rows side by side (even if it means planting in a square block) for good pollination. Lesson learned! I’d remember the next spring!

Suddenly (as things always seem to happen in summer), I realized it must be getting close to harvest time! How did one go about drying the corn? And at what point does a person remove it from the cobs? This time, I followed my own advice about living life with others and showed reliance on a local gardener. Going back to the seed-giving friend, I asked for more details about the process. What did it boil down to? I was supposed to:

  • Leave the corn attached to the stalk for long as possible, but harvest before the frost. If winter hits with a wet, rainy season, harvest to avoid decay.
  • Pull back the husks and expose the kernels to direct air
  • Either remove husks completely and bind corn in groups of 6-8 or tightly tie husks together (remember, they’ll shrink!) with baling twine for hanging. 
  • To dry, hang in a place that is out of direct sunlight, preferably in a warm area with good airflow
  • When kernels are rock hard and you are unable to dent them with a fingernail, they are ready for removal.
  • You don’t have to remove them immediately! If you want it done at once, have a corn shelling party with friends or, you are not in a rush, take it at your own leisurely winter pace, shelling as you have time.

I did just that. Stripping the stalks of ears after they seemed quite dry on the plant (even in a northern climates they usually dry out before frost hits), I tossed the them into a gunny sack and lugged them up the hill to home. We have a back room that is rarely used for anything. There, from brackets on the wall I hung my corn. Pulling back the husks to expose kernels to the air, I tied strips of cloth (I’d recommend using string) around the rustling, fuzzy greens. With the corn tips point to the floor, they hung to dry. The first time, I didn’t tie them tight enough. As the husk dried out, the corn ears began slipping. One day they fell with a grand ‘boom’ on the hardwood floor. I tied them tighter and re-hung to continue drying. 

After Christmas, I decided it was time. Pulling the ears down, I cut off the dry, papery white husks. Once removed, I began attempting to remove the kernels. A deep red in color with slightly yellowing tips, they were beautiful and intriguing to look at! Perhaps one year I’ll save some whole ears just for decorative purpose! 

Excited to learn, I began the work. I had no idea that corn was so rough on the hands! This particular type had tiny hook-like points at the end of each kernel. They can very quickly rub the hand raw! Leather gloves are a wonderful option!

Taking an ear of dried corn, I gripped it with both hand. Twisting one clockwise and the other, counter clockwise, kernels began popping off slowly at first, but then quicker as more of the cob was exposed. I’d recommend keeping an eye open for mold if stored in a damp place. If corn didn’t have proper ventilation, its entirely possible. The shelling was best done over a pan or large bowl to catch the falling kernels! If I were to have a corn shelling party, I’d spread a cloth over the table and have each person work directly on the cloth. From there it could be easily scooped into containers.


All too soon, it was over! Slipping the kernels into jars, I sealed them with lids and stashed them away on the pantry shelf. Paper or cloth bags will do just as well! Make certain corn is absolutely dry if sealing up in a container or jar.

Send your corn kernels through the grain mill just as you would wheat or smaller grains. Be sure to open up grinder’s width as far as it will go! One cup of corn kernels will make approximately 2 1/4 C of corn flour. Approximately 1/2-3/4 C of flour will thicken 4-5 C broth.
