Why tie rib roast?

Rib roast is tied to maintain its shape during the roasting process. The twine helps to hold the roast together, preventing it from falling apart or losing its shape. Furthermore, tying the rib roast helps to create a more even cooking surface, ensuring that all sides of the roast are cooked evenly. Additionally, tying the roast helps to keep the juices inside, resulting in a more flavorful and tender roast. Finally, tying the rib roast allows for easier slicing after it has been cooked.
