1. In a large bowl, combine warm water and sugar. Sprinkle in the yeast and let it sit for about 5 minutes, or until foamy.

2. Stir in melted butter and salt, then gradually add the flour, one cup at a time. Mix until a dough begins to form.

3. Turn the dough onto a lightly floured surface and knead for 8–10 minutes until smooth and elastic. If it’s sticky, add a tablespoon of flour at a time.

4. Grease a large bowl with olive oil and place the dough inside. Cover with a damp towel and let it rise in a warm place for about 1 hour, or until doubled in size.

5. Punch down the dough and shape it into a loaf. Place it in a greased 9×5-inch loaf pan.

6. Cover the loaf with a towel and let rise again for about 30–40 minutes, until the dough has risen about 1 inch above the pan.

7. Preheat oven to 350°F (175°C). Brush the top with egg wash (1 egg + 1 tablespoon water).

8. Bake for 30–35 minutes, until golden brown and the loaf sounds hollow when tapped.

9. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
