How I made
In a bowl of kitchen aid stand mixer combine the instant yeast with the remaining ingredients, and mix till clumps form; the dough may seem dry at this point. Let it rest for 20 minutes, for the flour to start to absorb the liquid.
Knead the dough using dough hook by mixer to make stiff, but fairly smooth dough. It'll take about 7 minutes in a stand mixer at second speed, using the dough hook. The dough should clean the sides of the bowl; if it doesn't sprinkle in a bit more all-purpose flour.
Place the dough in a lightly greased bowl, cover the bowl, and let the dough rise till it's puffy, about 1 .30 hours. It may or may not have doubled in bulk, but it definitely will have expanded.
Gently deflate the dough, and shape it into a log. Place the log in a lightly greased 9" x 5" loaf pan. Press it to the edges of the pan, and flatten the top.
Tent the pan with greased plastic wrap, and allow the loaf to rise till it's crowned about 1" to 1 1/2" over the edge of the pan, about 1 to 1 1/2 hours. Towards the end of the rising time, preheat the oven to 350°F. Keep an empty broiler pan in the lower rack of oven. Add boiling hot water into the broiler pan when you are ready to bake the bread. (This will create steam, necessary to make the thick crust).
Bake the bread for 20 minutes. Tent it lightly with foil, and bake for an additional 20 minutes. When done the bread will are golden brown and its internal temperature will register 190°F on an instant-read thermometer.
Remove the bread from the oven, wait 5 minutes, remove it from the pan, and allow it to cool completely on a rack before slicing. Store for up to a week at cool room temperature.
