What are the ingredients for bun?

The basic ingredients for making a bun typically include all-purpose flour, water, yeast, sugar, salt, and fat (such as butter or oil). Some recipes may also include milk or eggs for added richness. The dough is usually mixed, kneaded, allowed to rise, shaped, and then baked until golden brown. Variations may include additional flavorings or toppings, depending on the type of bun being made.
