1. In a large mixing bowl, combine the warm water, active dry yeast, and granulated sugar. Stir gently and let it sit for 5-10 minutes until the mixture becomes foamy. This foaminess indicates that your yeast is active and ready to work.

2. To the yeast mixture, add the salt, 2 cups of the all-purpose flour, raisins, and ground cinnamon. Stir with a wooden spoon or a sturdy spatula until a shaggy dough forms.

3. Gradually add the remaining 1 cup of flour, a little at a time, until the dough is less sticky but still soft. Turn the dough out onto a lightly floured surface and knead for about 5-7 minutes. You’re looking for a dough that is smooth and elastic. It should spring back slowly when poked.

4. Lightly grease a clean large bowl with olive oil. Place the dough in the bowl, turning it once to coat all sides. Cover the bowl with plastic wrap or a clean kitchen towel and let it rise in a warm, draft-free place for 1.5 to 2 hours, or until it has doubled in size.

5. About 30 minutes before the end of the rise time, place your empty Dutch oven with its lid into your oven and preheat to 450 F (230 C). This ensures the Dutch oven is scorching hot, which is crucial for a great crust.

6. Carefully remove the hot Dutch oven from the oven. Lightly dust the bottom with a little flour. Gently transfer the risen dough into the hot Dutch oven. Score the top of the dough with a sharp knife or razor blade (a simple “X” or a few parallel lines work well). This helps the bread expand evenly.

7. Place the lid back on the Dutch oven and bake for 30 minutes.

8. Remove the lid and continue baking for another 10-15 minutes, or until the crust is deeply golden brown and sounds hollow when tapped on the bottom. If desired, brush the top with melted butter and sprinkle with a little sugar during the last 5 minutes of baking for an extra sweet, shiny finish.

9. Carefully remove the bread from the Dutch oven and transfer it to a wire rack. Allow it to cool for at least 30 minutes before slicing. This cooling time is essential for the internal structure of the bread to set and for the flavors to fully develop.
