Combine flour and salt. Cut in butter with a pastry cutter until mixture resembles bread crumbs.

Add yeast liquid and beaten egg to flour mixture and stir with wooden spoon to form a dough.

Turn out onto a floured surface and knead for 5-6 minutes. Place in a floured bowl and cover with a towel. Leave in warm place until double in size (about 1 hour).

Turn dough out onto a greased pizza pan or a 9x12 inch baking sheet. Press out to edge of pan with fingers and form a lip around the edge. Top with sauce, cheese and your favorite toppings. Bake at 425 degrees for 18 minutes.
