Activate the Yeast: In a small bowl, dissolve the sugar in warm water. Sprinkle the yeast over the water and let it sit for about 5-10 minutes. The mixture should become frothy as the yeast activates.
Prepare the Dough: In a large mixing bowl, combine the flour and salt. Create a well in the center and pour in the yeast mixture along with the sunflower oil. Stir the ingredients together until they begin to form a dough.
Knead the Dough: Transfer the dough to a lightly floured surface. Knead it for about 8-10 minutes, until the dough becomes smooth and elastic. Add more flour as needed to prevent sticking.
First Rise: Place the kneaded dough into a greased bowl and cover it with a damp cloth. Let the dough rise in a warm place for about 1 to 1.5 hours, or until it has doubled in size.
Shape the Dough: Once the dough has risen, punch it down gently to release the air. Shape the dough into a loaf by folding the edges inwards and rolling it into a log shape. Place the shaped dough into a greased loaf pan.
Second Rise: Cover the loaf with a damp cloth and let it rise for another 30-45 minutes, or until it has risen slightly above the edge of the pan.
Bake the Bread: Preheat the oven to 375°F (190°C). Bake the loaf for 25-30 minutes, or until the bread is golden brown on top and sounds hollow when tapped on the bottom.
Cool and Slice: Remove the bread from the oven and allow it to cool on a wire rack before slicing. Enjoy warm with your favorite spread or topping.
