Chefs in restaurants use spoons to cook because it is a more effective and controllable cooking tool. The design of the spoon enables it to better stir and rotate dishes, thus ensuring that they are evenly heated and cooked. Compared with other tools, the spoon can also better control the moving and turning speed of dishes and avoid overcooking or frying food.

In addition, using a spoon can better protect the shape and texture of ingredients, because it will not exert too much pressure or damage on them like using a shovel or clip. This is especially important for some exquisite dishes, such as scrambled eggs, fried rice and fried noodles.

Finally, the spoon is also a very flexible tool, which can be used to stir, season and scoop up ingredients. This allows the chef to perform multiple cooking steps in the same pot without changing tools frequently.

In short, chefs in restaurants use spoons to cook because spoons are more effective, controllable, gentler and more flexible food tools. These characteristics are very suitable for cooking in a stressful and demanding kitchen environment, thus ensuring that customers can enjoy delicious and healthy meals.
