The utensils in our kitchen portray the amount of cooking done in our house. If the utensils and glassware look sparkling clean with the labels still on, you can make out that this family survives on reheated frozen food.
But sometimes our experiments in cooking can lead to burnt food (and no dinner!). This can be remedied by adding some chopped onions to the vessel and pouring some boiling water over it. You need to let it stay that way for five minutes and then wash off. The vessel will be clean and all the burnt food particles will be removed.
