In Mexico, street vendors sell corn on the cob from carts like vendors in the U.S. sell hot dogs. The corn is served coated with either melted butter, chili powder and lime juice, or a creamy cheesy mixture consisting of a crema (a tangy cultured sour cream) or maynnaise mixed with chili powder and garlic. The mixture is slathered over the corn and then sprinkled with a crumbly Mexican cheese such as queso anejo or queso fresco. This recipe came from "The Best of America's Test Kitchen 2009" If possible, leave the stalks on the corn attached; they make nice handles when cooking and eating. Edited on 4-14-09...The last time we prepared this recipe, we used our stove top smoker and smoked the corn for about 25 minutes, then finished them off in the broiler with the mayo/cheese mixture. If you have a stove top smoker, this is definitely the way to go, the corn was amazing!
