Many people assume that soft sandwich bread must contain butter, milk, eggs, or even special bread improvers.
In reality, traditional bakery bread achieves its texture through proper dough development and fermentation rather than rich ingredients.
As you knead the dough, gluten forms a strong yet flexible network that traps carbon dioxide produced by the yeast. During fermentation, thousands of tiny gas cells develop inside the dough. In the oven, these cells expand rapidly, creating a loaf that is light, even, and pleasantly fluffy.
That is why this recipe has remained popular for generations. It relies on technique rather than complicated ingredients.
