Start by measuring all of the ingredients into the stand mixer.
Using the dough hook attachment on low, mix the dough until all ingredients are combined, about 6 minutes.
Cover the bowl and allow to rest for 5 minutes.
Restart the mixer on low for 2 minutes. The dough should become a smooth ball and come up from the bottom of the bowl.
Wet a tea towel with very hot water and wring out as much water as possible.
Remove mixing bowl from mixer and cover with dampened towel.
Place bowl in a warm place to rise overnight. This can take anywhere from 9-12 hours depending on the temperature of the house. It rises faster in the summer and slower in the winter.
The next morning, the dough should be double in size.
Remove dough from the bowl and form into a ball. Measure the weight of the dough and cut in half. It should be approximately 1 kg each.
Stretch one dough ball in a rectangle approximately 8 inches by 14 inches. Roll the dough, pinching and folding the sides, into a loaf shape. Pinch the bottom into the dough to remove the crease and place in a buttered loaf pan. Repeat with the second loaf.
Cover the loaves with the tea towel and allow to rise for 2-4 hours. Again, the room temperature will affect the rising time.
When dough is risen slightly above the rim of the bread pan, it is ready to bake. Preheat the oven to 350 degrees.
Bake both loaves for 45 minutes, or until internal temperature of bread is 190 degrees.
Remove loaves from oven and cool on cooling rack for 5 minutes. While bread is cooling in the bread pan, smear butter all over the tops of the loaves.
After 5 minutes, the bread pans and loaves will still be very hot. Carefully remove loaves from the bread pans and allow to fully cool on the cooling rack for 1 hour before cutting.
