Given the esteem of corn smut in Mexican cookery, I've always wondered about the taste and how to cook it. Apparently some folks call it a corn truffle. Whoa! Can't wait to hear the results of your adventure.
Meanwhile, why don't a few Iowa farmers specialize in making corn smut by the ton? Inertia is the answer, or tradition if that's a kinder word. But, grow it here, in corn country, and sell it elsewhere.
