In a large bowl, combine the hot water, butter, sugar, and salt. Stir until the butter is melted. Let cool to about 110 degrees F (45 degrees C).
Stir in the yeast, then cover and set in a warm place until bubbly, about 15 minutes.
Beat in about 5 cups of flour to make a thick batter. Stir in about 3 1/2 cups more flour to make a stiff dough. Scrape the dough onto a floured board. Knead until smooth and satiny, about 10 minutes, adding as little flour as possible to prevent sticking.
Place the dough in a greased bowl then turn it over to grease the top. Cover and let rise in a warm place until doubled, this takes about 1 1/2 hours.
Punch the dough down and knead briefly on a floured board to release the air. Shape into a smooth ball or into rolls.
Melt the additional butter in the bottom of both the Dutch oven. Place the dough or rolls, rolled in butter, in the Dutch ovens then nd cover with the lid. Let rise in a warm place until the dough rises, about 30 minutes.
Bake, covered, with a lid in a 350 degree F (175 degrees C) oven for 45 minutes or until the loaf or rolls sound hollow when tapped on the bottom.
