Hamburger buns are soft, round bread rolls specifically designed to hold a hamburger patty and its toppings. They are typically made from flour, water, yeast, sugar, and salt, which are mixed and baked to create a light and fluffy texture. Buns can be found in various styles, including sesame seed, whole wheat, and gluten-free options. These buns serve an important purpose in a hamburger meal, providing a convenient way to hold the ingredients together while adding flavor and texture. They are often toasted or grilled to enhance their taste and can be used for other sandwiches as well.
