While both 00 flour and bread flour often have a high protein content, they serve different purposes in baking. 00 flour is finely milled and is typically used for recipes that require a soft and delicate texture, like Neapolitan pizzas. Bread flour, on the other hand, has a coarser texture and is designed to provide strength and elasticity to doughs, making it ideal for breads that need a good rise. While there's some overlap in their uses, it's essential to choose the flour that aligns best with the desired outcome of your recipe.
