Foodservice guru Peter Backman of Horizons is just back from the Chicago National Restaurateurs Association Show and reports:
"The American consumer has been persuaded that gluten-freedom is the path to a happy life and consequently gluten free is all the rage. You want gluten free bread of course - you can have hamburger buns, sub buns, hot dog buns, muffins, cookies, desserts (including gluten free mudslide pie) - and more".
