HOW TO MAKE HOMEMADE SOURDOUGH BREAD
Makes 1 loaf

INGREDIENTS
Starter
2 cups warm water
1¼ teaspoon (1 packet) dry yeast
3½ cups flour
1 tablespoon sugar

Bread
4 cups flour
2 teaspoon salt
1¼ cup water
1 cup starter, stir before using

PREPARATION
In a glass bowl, add water and yeast. Mix the yeast into the water and let it sit for a couple minutes.
Add in the rest of the ingredients for the starter. Mix well until everything is fully incorporated.
Wrap the bowl with clear wrap, making sure not to tightly seal the bowl. Let the starter breathe a little and keep it in a dark place at room temperature. Stir once a day for 5 days until making the dough. The starter will rise and shrink each day and you should see bubbles, letting you know that the yeast is being activated! On day 5, combine all ingredients into a bowl, and knead for 10 minutes on low if using a machine; if kneading by hand, knead for 20 minutes until dough is stretchy yet doesn?t stick to your hands.
Place kneaded dough into a large bowl with a towel over the top, and let it rise for 12 hours.
Place risen dough onto a floured board and knead for a few minutes. Place it into a proofing basket or a medium bowl and let it rise for another 4 hours.
Preheat oven to 480°F/250°C.
Flip the dough onto a parchment paper, and transfer the dough and paper into a large cast-iron dutch oven.
Score the top of the bread.
Place the lid on top and bake for 30 minutes.
Take the lid off and bak...
