Mine turned out a little tough and dry. Also, I had never heard of XXX sugar (is that naughty sugar?). Apparently, it is a super fine granulated sugar. Since I don't have much call for that in other recipes, I just made a powdered sugar glaze. Who cares?
In mixing bowl, dissolve yeast in warm water, let stand for 5 min. In a saucepan, heat milk and orange juice to 110', add to yeast mixture, Stir in 1/2 cup sugar, orange peel, slat, egg and 3 cups flour; beat until smooth. Add enough remaining flour to form a soft dough.
