Mix salt, yeast and water. Stir until dissolved.
Add flour. Mix until well blended.
Cover in a bowl with plastic wrap, leaving a small hole in the plastic wrap.
Let rise 2 hours.
Sprinkle a small amount of flour on top and punch down.
Divide dough in half to make two balls, using just enough flour so you can make each into a ball. It will be sticky.
Fold the edges under to form a smooth top.
Let rise on parchment paper on a cookie sheet for 40-50 minutes until doubled.
Optional: Put melted butter on top with some sesame seeds. Score the top of the bread with a knife. Place an oven-safe pan with 1 cup of water in oven. (The steam this creates will give the bread a chewy, crispy crust.)
Preheat oven to 450°.
Bake 30 minutes.
