Heat the milk in a small saucepan until it bubbles, then remove from heat. Mix in butter; stir until melted. Let cool until lukewarm.
In a large mixing bowl, combine 2 1/4 cup flour, yeast, sugar and salt; mix well. Add water, egg and the milk/yeast mixture; beat well. Add the remaining flour, 1/2 cup at a time, stirring well after each addition.

Roll out dough into a 15×10 inch rectangle.
