A handful of us Bud-swilling, queso-consuming, Janet Jackson's boob-ogling partygoers powered through about a pound of the new black and white M&M's on Super Bowl Sunday. As you must already know, the different colored candy-coated chocolates don't taste noticeably different from each other. This is not surprising. But you might get a kick out of testing yourself the next time you sit down to a basket of tricolor tortilla chips. Because blue corn chips are made from a different kind of corn it seems logical that they might not taste exactly like white or yellow chips. And the bright red chips, which might be made with red corn but must also use some food coloring, have a completely novel flavor. While you're waiting for your food to come, eat a few regular white or yellow chips just to familiarize yourself with the flavor. Then break off three similar-sized chunks of the different colored chips into your hand. Close your eyes and shuffle them around a bit then pop one in your mouth. Chew it up and try to guess which one you're eating. You'll probably recognize the regular chip right away. Blue corn chips are often denser, grainier with a more earthy flavor. The red chips are mellower, almost sweet. There, that's your new party trick. I hope it wins you a few bets and a free margarita or two.
