A loaf is a shaped mass of bread that is typically baked in an oven. It can be made from various types of flour, water, yeast, and salt, and may include additional ingredients like seeds, nuts, or fruits. Loaves come in different sizes and shapes, such as round, oval, or rectangular, and are often sliced for easy serving. In addition to traditional wheat bread, there are many variations of loaves, including sourdough, rye, and gluten-free options. Loaves are commonly used for sandwiches, toast, or as a side dish for meals. They are a staple food in many cultures around the world.
