2-1/4 teaspoon active dry yeast, 1 cup warm water, 1/4 cup sugar, 2 teaspoons olive oil
Whisk in egg. Combine salt and flour and add to yeast mixture. Add enough flour so that you can handle the dough. Knead until smooth.
4-1/2 cup unbleached all purpose flour, 1 egg, 1/2 tablespoon salt

1/2 cup butter, 1/2 cup granulated sugar, 2 tablespoons cinnamon powder
