Bisquick was invented by a train chef to help him quickly whip up biscuits for late boarding passengers. Traditional Bisquick is a premixed baking product consisting of flour, shortening, salt and leavening originally intended for making biscuits. The new Bisquick Gluten Free Pancake and Baking Mix is not Bisquick in its traditional sense, as it’s missing the shortening. Instead it’s blend of rice flour, sugar and leavening. The Bisquick Gluten Free Pancake and Baking Mix is available in supermarkets nationwide, retailing for $4.49 per 16-oz box.
