Add warm water and beat by hand about 300 strokes, or 3 minutes, with an electric mixer. Add remaining flour, scraping bowl often, and mix all together until smooth.
Cover with a clean cloth and let rise until doubled in volume, approximately 1 hour..
Stir dough down gently, and spoon into a lightly greased 9 by 5 inch loaf pan (the batter should be sticky). Pat down with floured hands to help shape. Cover again, and let rise.
Preheat oven to 375 degrees while dough is rising the second time. When dough has doubled (about 30 minutes) bake for about 45 minutes.
Place on a cooling rack, and brush top with 1 tablespoon melted butter.
