When Corn Tastes like a Mushroom



Recently, one of members found something special when she purchased corn at a market.  The surprise? Corn smut!  She purchased some fresh ears of corn from a market and later in the day she started to remove the husks.  When she removed the husk from the last ear of corn she had a surprise which she initially thought was a huge insect and she quickly threw the ear of corn into the sink.  When the object didn't budge, she decided to live dangerously and pressed it with her finger to see if it would move.  No, it didn't move. Upon closer examination, it looked a little like mold in certain spots.  So she decided to do what all good "Crop Scouts" do... she Googled it!


Imagine her  surprise when she discovered that corn smut(Ustilago maydis) is a delicacy in Mexico.  A brief perusal of the literature revealed that in some urban markets Huatlicoche sells for $25 per pound.  Chefs in many of the larger cities have incorporated Huatlicoche into their menus. In 1989 the James Beard Foundation held a dinner in its honor, christening it "Mexican truffle" to promote its prestige. It sort of worked. In the '90s the USDA, responding to demand, cleared Florida and Pennsylvania to infect crops with the parasitic fungus. 

Here are some pictures of Ustilago maydis on the ear of corn.






So, the next time you are eating Huatlicoche at that upscale city restaurant remember the fungus that made your gourmet meal possible.
