In Minnesota we used to say that the corn ought to be knee high by the forth of July. In California the corn is sweet and ready to eat by July. Not sure what the corn is doing here on the East coast. I recently read that corn "engenders happiness." There's a good reason to bring it on your next picnic or serve for dinner!
The next time you steam a few ears or cook them on the grill, skip the butter and rub Ume paste (http://www.simply-natural.biz/Ryujin-Ume-Paste.php) on your corn. It’s delicious and much better for your digestion as well as your heart.
