Scoring razor or small serrated knife, such as a steak knife or utility knife
Ingredients
1packet (7g or 2 1/4 tsp) instant yeast
1tbspsalt
2cwarm waterabout 100 degrees F
4call-purpose flourplus more for sprinkling
1tbspcornmeal/semolina flour
1cadditional water
Instructions
Put the active yeast and salt into the warm water and barely stir so all the yeast gets wet (it’s alright if it's a bit clumpy). Set aside for 5 minutes to "bloom."
Wash your hands really well.
Add the flour to a large mixing bowl. Form a well in the center and pour in the yeast water.
Mix together by hand until the dough just barely comes together.
Leave the ball in the mixing bowl, cover the bowl with a kitchen towel, and let rise at room temperature (preferably in a warm corner of your kitchen) for 2 hours, or up to 5 hours.
Prepare a baking sheet, pizza peel, or other flat, food-safe object by sprinkling cornmeal/semolina flour over it.
Optional: Uncover the dough, and place it on a lightly floured surface. Use a sharp knife or dough cutter to cut the dough in half. If not baking all the dough, flour some plastic wrap and wrap it around the excess dough. Refrigerated dough can be used for up to two weeks.
Take the dough you’re baking and gather it in your hands, smoothing over the top until the dough is mostly rounded on top and lumpy underneath. Feel free to pat more flour on the dough as you go, as it will be sticky.
Place the dough on the baking sheet covered in cornmeal.
Cover with a kitchen towel again and let proof for another 40 minutes. Note: If using refrigerated dough, proof for 1 hour instead of 40 minutes.
While the dough is proving, adjust the racks in your oven so that one is at the bottom and one is in the middle. Place the pizza stone on the middle rack, and a 9x13” pan in the bottom.
Preheat the oven to 450℉. You’ll want to do this at least 20 minutes before the bread goes in so the stone heats properly.
When the dough is ready, take a sharp knife or baking razor and score (make shallow lines in) the top at least 3 times.
Carefully transfer the bread from the baking sheet to the hot pizza stone (a wide spatula helps).
Pour 1 c of water into the pan on the bottom rack. Shut the oven door as quickly as possible so the oven gets nice and steamy.
Bake for 60 minutes, or until the outside is a lovely golden brown.
Let cool for 10 minutes before slicing and eating with a generous heaping of butter.
