Step 1 In the bowl of a stand mixer, or in a large bowl, combine the yeast and one-half cup water with 2 tablespoons flour. Set aside until the yeast begins to bubble, 5 to 10 minutes.
Step 2 Using the paddle attachment, or with a hand mixer, blend in the remaining water and egg until combined. With the mixer running, add the margarine and sugar.
Step 3Stir in the flour, a spoonful at a time, until incorporated. Remove the dough to a lightly floured board and knead until soft and elastic, 8 to 10 minutes.
Step 4Place the dough in a large, oiled bowl and loosely cover. Set aside until doubled in size, about an hour.
