In a mixing bowl, stir together the water, melted shortening, salt, and sugar.
Sprinkle the yeast over the top of the mixture and let it stand until the yeast dissolves and starts bubbling a bit, about 10 minutes.
Stir in half of the flour (1½ cups flour for each loaf) and beat until smooth.
You can use an electric mixer for this part if desired, but you can also mix by hand using a large wooden spoon.
Add enough of the remaining flour to make a dough ball that holds together and comes away from the sides of the bowl.
Place the dough onto a floured work surface and knead well for 5 to 10 minutes, adding more flour as needed to keep the dough from sticking.
Put the dough into a large greased bowl and grease all the surfaces of the dough as well.
Cover it with a towel and let it rise until double, about 1 to 1½ hours.
Punch down and then lightly knead the dough for a minute or so, grease all the surfaces once again, and let it rise in the greased bowl a second time until double.
Punch down the dough and form into a loaf (or however many loaves you’ve decided to make).
Place the loaf seam side down into a greased loaf pan and let it rise until almost double, about 45 minutes.
Preheat the oven to 400°.
Place the loaf in the preheated oven and then immediately turn the heat down to 350°.
Bake about 30 minutes or until done.
Remove the loaf from the oven, grease the top if desired, take it out of the baking pan, and cool on a wire rack.
