I think it has the following importance! First of all, if you are not sure about the cooking time! Then the taste must be bad, and you may not be able to eat it! If you grasp it well! How can you be sure it's particularly delicious? It can't get any worse. Of course, in cooking, fire is really important! If you are not sure about this, it is estimated that all dishes should be invalid, just a waste, just a dish!

Under normal circumstances, if you eat it yourself, you can cook it yourself, but if you sell it in a restaurant, you don't know much about the temperature. It is estimated that no one will pay the bill! Such a store is estimated to be closed down!
