,I have observéd that you very often use an aluminum pan when you use tomatoes for cooking. Please take note that the acid contained in tomatoes can react with the aluminum pan It is not good for the health. You seem to think that cooking tomatoes in an aluminum pot or pan for a lesser time does not cause health problems. It is a wrong notion. As a person doing cooking videos on utube you should be more careful about what you present to the general public because people who are not aware of these health hazards might follow your wrong example.
