Cooking Tips: To reheat hard or stale bread, dip it in some warm water and bake at 180°C until it is well warmed. If it is fluffy, then wrap it in aluminum foil and place it in the oven for 5 minutes at 200°C.
A bread is a staple food made from a mixture of ground grains or seeds (flour), salt and water, baked grilled or fried to a solid mass. Now usually refers to wheat or rye flours but other grains are used in small quantities and ground legumes in India. Bread is either unleavened or leavened. Leavening introduces small bubbles of gas into the flour water matrix giving the bread a lighter texture.
