In a mixing bowl, combine the active dry yeast with 1 cup of warm water. Let it sit for about 5-10 minutes until it becomes frothy.
In a separate bowl, whisk together 3 cups of all-purpose flour and 1 teaspoon of salt.
Once the yeast mixture is frothy, slowly add the flour mixture to the yeast, stirring until a rough dough forms.
Transfer the dough onto a floured surface and knead it for about 10 minutes until it becomes smooth and elastic.
Place the kneaded dough into a lightly greased bowl, cover it with a kitchen towel, and let it rise in a warm place for about 1 hour or until it has doubled in size.
Once risen, punch down the dough to release the air. Divide the dough into equal portions and shape each into a round loaf.
Place the shaped loaves on a baking sheet lined with parchment paper. Cover them with a towel and let them rise for another 30 minutes.
Preheat your oven to 375°F (190°C). In a small bowl, whisk the egg and 1 tablespoon of flour together. Brush the mixture over the loaves.
Sprinkle the tops of the loaves with sesame seeds.
Bake the loaves in the preheated oven for 20-25 minutes or until they are golden brown and sound hollow when tapped on the bottom.
Remove the bread from the oven and let it cool on a wire rack.
