The underlying theme of breadmaking is keeping the yeast happy by providing a good growth medium.
Yeast makes carbon dioxide gas that acts as a leavening agent.
Start by proofing or growing the yeast. Yeast requires a warm, wet, environment and a food source to multiply and thrive. The water should feel warm, not hot, to the touch. Provide a food source, a little sugar or honey. Set the yeast aside until the mixture resembles a creamy foam.
