We might smell bread, and the smell of new bread is wonderful, but once again the smell is not the bread, but simply a property. This is true of bread, it is true of every created thing. If left to spoil, the accidents have thoroughly changed. Yes it did, the steak is now garbage, the substance not good for food. We eat substance, not accidents.
Water also proves the distinction specious, of the order of myth.
Water can be liquid or steam, depending upon what accidents exist. That the substance changed is easily seen by the fact steam cannot exist in water, only in air. They are therefore incompatible. So when accidents change substance changes. Explain how this is not so.
