• In a large mixing bowl, combine 2 and 1/4 cup all-purpose flour, sugar, salt and active dry yeast. Whisk well.
• In a microwave-safe bowl, microwave butter, milk and water until the butter melts. The temperature of the mixture should be between 110-115 F. Re-heat in the microwave when necessary. 
• Add the butter mixture to the dry ingredients in the mixing bowl. Stir the mixture using a wooden spoon until incorporated. Add the egg and stir. Add some of the reserved flour gradually while stirring until the mixture turns into a soft dough that gathers in the center of the bowl. You may not need all the flour.
• Turn the dough onto a floured board and knead for 6-12 minutes, until it is smooth and elastic. Let the dough rest for ten minutes in a bowl, covered.
• Roll the dough using a rolling pin into a 14x10 inch rectangle. Spread the ube across the dough. Roll the short side of the dough to form a tight log. Cut the log into 4 equal portions using a sharp knife. Arrange the portions, cut side up in a greased 9x5 loaf pan.
• To let the rolls rise, preheat oven to 200 F. Once the temperature is reached, turn OFF the oven and put the ube loaf inside. Let it rise for 60-90 minutes, or until the size is doubled. Take the ube loaf out of the oven. Preheat oven to 350 F. Brush the surface with egg wash. Bake the loaf for 18-22 minutes or until the top is golden.

Egg wash

• Beat one tablespoon of milk with 1 egg. Brush on the surface of the ube loaf.
