Like the instruments in an orchestra, the ingredients in basic bread are very simple: flour, sugar, salt, a liquid (such as water or milk), possibly a fat (such as butter or oil), and yeast. And, like each musical instrument, each ingredient performs a specific job, and each lends a special flavor to the final masterpiece. That's why it's important to use the right ingredients in exactly the right proportions to ensure you get the most delicious results!
