In a small bowl dissolve yeast in 1/2 cup of warm water
In a large bowl, mix 2 cups hot water, sugar, butter, salt and half the flour
Once the yeast is foamy, add it to the flour mixture and incorporate everything well.
Switch to dough hook attachment and add the remaining 3 cups of flour. Let the dough hook mix for 5 minutes until flour is incorporated and dough is smooth and elastic.
Turn off the mixer and allow the dough to sit for 10 minutes covered with a tea towel
After 10 minutes, punch down the dough with a wooden spoon and cover for another 10 minutes. Repeat this process 5 times.
Pour the dough on a floured counter and divide in half (or fourths). Roll each piece into a rectangle like you're making cinnamon rolls. Roll the dough lengthwise and and tuck the ends under.
Place the loaves on a baking sheet covered in parchment and allow them to rise for another 20-30 minutes.
Score the loaves with small slits across the top.
Create an egg wash by cracking an egg and beating it with a few drops of water. Brush this over the loaves to create the beautiful color.
Bake the loaves at 375 for 20-25 minutes
