In a small bowl, combine warm water and sugar. Stir until sugar dissolves. Sprinkle yeast over the water and let it sit for about 5 minutes until it becomes frothy.
In a large mixing bowl, combine the flour and salt. Make a well in the center and pour in the activated yeast mixture.
Mix the ingredients until a dough forms. Knead the dough on a floured surface for about 10 minutes until it becomes smooth and elastic.
Place the dough in a lightly oiled bowl, cover it with a clean kitchen towel, and let it rise in a warm place for about 1 hour or until doubled in size. The slow rise as you let the dough rest will give you the best crackly crust French bread.
Preheat your oven to 450°F (230°C). Punch down the risen dough and divide it into two equal portions.
Shape each portion into a baguette shape and place them on a lightly floured or parchment-lined baking sheet. Score the tops with a sharp knife.
Allow the baguettes to rise for an additional 15-20 minutes. Bake in the preheated hot oven for 20-25 minutes or until golden brown for a nice crispy crust. Cool on a wire rack before slicing.
