Preparation

In a 2-cup liquid measure, dissolve 2 teaspoons sugar and yeast in warm water. Let stand until foamy, about 5 minutes. Insert the dough blade in the work bowl and add flour, remaining sugar and salt. Pulse to combine, about 2 to 3 times. Add cold water, melted butter and egg to yeast mixture. With machine running, add liquid through small feed tube in a steady stream as fast as the flour absorbs it. Once dough forms a ball continue processing for 45 seconds to knead dough. Place dough in a floured plastic food storage bag and seal. Let rise in a warm place until doubled in size, about 1 to 1½ hours. Place dough on a lightly floured surface and punch down. Divide dough into 3 equal pieces. Use your hands to roll each piece into a cylinder about 1½ x 14-inch. Place the cylinders side by side on a baking sheet coated with vegetable oil cooking spray. Braid loosely from one end. Gently pull and taper each end to a point, then pinch and tuck under loaf. Cover with plastic wrap coated with vegetable oil cooking spray and let rise until doubled in size, about 45 minutes. Preheat oven to 375°F 15 minutes before baking. Prepare egg glaze by combining egg with water; brush over braid. Bake in lower third of preheated oven for 20 minutes. Lower temperature to 350°F. and bake until loaf is browned and sounds hollow when tapped, about 10 minutes. Cool on wire rack.
