In the bowl of a food processor, combine yeast, flour, salt, and 1 teaspoon sugar. Process until combined.
With machine running, slowly pour in warm water. Once water is added, continue processing until dough comes together into a ball, around 30-45 seconds.
Place dough in an oiled bowl and cover with a flour sack towel or plastic wrap.
Let rise in a warm place for 1 hour or until doubled.
Heat oven to 375 degrees Fahrenheit. After dough has risen, punch down.
Place dough on a piece of parchment paper and divide into 2 pieces.
Make 2 long, skinny ropes of dough, about 20 inches long.
Twist the 2 ropes together.
Form twist into a ring. Place on parchment paper on a baking sheet.
Nestle 3 eggs between twists in dough.
Beat remaining egg with 1 tablespoon water. In a separate container, stir together 1 tablespoon sugar with 1 teaspoon cinnamon.
Brush egg wash over formed loaf.
Sprinkle cinnamon topping over bread.
Bake bread for 25 to 30 minutes, until golden brown.
