Step 1

Combine water, salt, yeast, garlic, and rosemary in a mixing bowl. Stir in flour.

Step 2

Cover with a damp kitchen towel and allow to sit at room temperature for 8-24 hours. It will become bubbly.

Step 3

Dust a sheet of parchment paper with flour. Turn dough out onto parchment paper and form a ball bay tucking the loose "edges" of the dough under. Allow to rest for 30 minutes.

Step 4

While dough is resting, place a deep, lidded casserole dish or cast iron Dutch oven in the oven and preheat to 450 degrees Fº.

Step 5

Use a sharp knife to make an "X" in the top of the loaf.

Step 6

Transfer bread to the hot baking dish and cover.

Step 7

Bake for 30 minutes. Uncover and bake for 15 more minutes, until the bread is nicely browned.

Step 8

Remove from oven and cool before slicing.
