In a bowl mix hot milk and saffron and 1 teaspoon sugar and set aside.
DOUGH
In a kitchen aid stand mixer add all the ingredients except the butter knead with dough hook to form a cohesive, sticky mass, 2 to 3 minutes on low speed of a stand mixer.
Gradually add butter and incorporate about 1 minute on low speed. Once all
the butter is incorporated, turn the mixer up one speed and knead the dough
until it is smooth and supple though still somewhat soft and tacky, about 2 to 3 minutes.
Cover the dough and let it rest in a warm (75°F) place for 3--4 hours. To develop strength in the dough, stretch and fold it in the bowl three to four times during the rest. This will increase the elasticity of the dough.
Shape
Next morning divide the dough into 8 pieces of 85g.
Roll it into 12-inch snake and twist both ends.
After 35-40 minutes brush with egg wash and stick a raisin on both ends.
Bake it in 375°F for 25- 30 minutes or until golden in color.
Enjoy, it is excellent breakfast bread on its own.
