In a large bowl (or Kitchen Aid bowl), dissolve the yeast in warm water. Add the milk, butter, sugar, egg yolk and salt.
Using a dough hook, slowly add the flour and beat on medium for 2-3 minutes until the dough forms a ball. It will pull away from the sides of the bowl
Take the dough out of Kitchen Aid and put on a floured surface and knead until elastic, approx 5 min. Add small amounts of flour if dough sticks to your surface
Place it in a greased LARGE bowl, turning once to grease both top and bottom and cover with clean cloth for 1 hour. (TIP: If your house is below 68 degrees try turning the oven on 100 for about 20 seconds and then turning off. Put the bowl in there and close the door and leave in oven to rise)
Take the dough out of the bowl (after it has risen) and punch it down. Put it on a lightly floured surface and divide it into thirds. Make 3 (20″) ropes. Place each rope on a greased baking sheet and braid. Pinch the ends to seal and tuck under. Cover again with cloth and let it rise for about 45 min
Combine your spices in a small bowl
Combine egg white and water; brush over dough and sprinkle with spices
Bake at 375 for 22-26 (or longer depending on your over) minutes until golden brown
