Soften yeast in 1/4 warm water.
Mix scalded milk with 1/2 cup sugar, shortening, salt, 1 Tbsp orange peel, and 3/4 cup orange juice; cool to lukewarm.
Stir in 2 cups of flour; beat smooth.
Stir in yeast and egg; beat well.
Add enough of the remaining flour to make a soft dough.
Turn out on lightly floured surface; kneed until smooth about 10 minutes.
Place in a greased bowl, turning dough once. Cover and let rise till double (1 1/4 hours).
Punch down; divide in half. Cover, and let rest 10 minutes.
Roll each half in 15x7 inch rectangles, 1/2 inch thick.
Combine 1/2 cup sugar with cinnamon. Spread each rectangle with half the sugar mixture.
Sprinkle each with 1 teaspoon water; smooth with spatula.
Roll. Seal edge; place sealed edge down in greased 8 1/2 x 4 1/2 x 2 1/2 inch loaf pan. Cover and let rise until double (1 hour).
Bake at 350 degrees for 30 minutes. Cool; frost with icing made of confectioners sugar, orange peel and orange juice. Drizzle icing from a spoon, moving it back and forth like "push-and-pulls" in penmanship.
