1. Combine sugar, salt, and yeast. Add water and let foam (indicating the yeast is alive). Add flour and mix well. Place in a bowl, cover, and let sit at room temperature to rise for 3-6 hours and up to 2 days (at that point, you might find it exploding out of the container). Punch down and shape into baguettes or place in refrigerator for up to 2 weeks.
2. Bake at 400F for 25-30 minutes. Makes 3 loaves.
