Add the shortening to the hot water and stir until melted.
In a large bowl, combine 5 cups of the flour with the salt, sugar, and yeast.
Gradually add the shortening mixture to the dry ingredients once it has cooled to lukewarm, mixing to form a dough.
Knead for about 5 minutes, gradually adding the remaining flour to form a stiff dough.
Place the dough in a greased bowl, cover, and let it rise until doubled in size.
Punch down the dough and divide it into portions. Shape each portion into a smooth ball, about 3 to 4 inches wide.
Place the rolls on a greased baking tray. Cover with a damp cloth and let them rise again until doubled in size.
Bake in a preheated 400°F oven for 15 to 20 minutes, until golden brown.
