How to Make Baguettes
A high baking temperature, a high ratio of water to solids, and allowing the mixture of flour, yeast, and water to rest 15 minutes (a process called autolyse) produce the baguette's airy interior and crunchy crust. Autolyse allows the flour to absorb water so the dough is less sticky when you knead it, which helps keep the texture light. Don't add too much flour when kneading and shaping the dough.
Step One: Divide the Dough
Divide the dough in half. Roll each on a floured surface into a 12-inch rope with slightly tapered ends.
Step Two: Preparing Dough to Rise
Place the ropes on a large baking sheet sprinkled with cornmeal. Lightly coat the dough with cooking spray. Cover, and let rise until the dough has doubled in size.
Step Three: Uncover and Bake Dough
Uncover the dough, and cut 3 (1/4-inch deep) diagonal slits across top of each loaf. Bake until loaves are browned on bottom and sound hollow when tapped.
