It depends what you’re going for. There are a lot of classic long simmered tomato sauces, they are a different thing than fast cooked ones though. Long cooked ones tend to be more mellow and complex, but lose some of the acidic zing, adding a bit of vinegar or wine at the end can bring that back though.
Just don’t make them in a cast iron, not only will the strip the seasoning, they will also absorb some iron, great if you have an iron deficiency, but it can make the sauce taste a bit metal-y.
Carbon steel is lighter but this also has less thermal mass, so it heats up and cools down faster, also tends to have less even heating.
So, searing something quickly on a preheated pan is a bit harder since the pan will cool off faster as the food leaches the heat out. Important for stuff like stir fry’s or steaks where you want short periods of intense heat for good searing at the surface but not over cooking in the interior.
