I was boiling milk in a pot and it overflowed and spilled, i inmediately took the pot of the stove and accidentaly placed it my great grandmothers metal serving tray we have as decoration. Now, she was not jewish and i dont know if it had absorbed non-kosher taste. (When i took it off the tray there was hot milk under it between the tray and the pot) what’s the din of the pot.
The pot is still kosher and you can use it. The reason is because any trief taste that was in the tray was already an eino ben yomo. Even though we can’t use it, in retrospect if it was used, it will not make anything trief.
