I poured hot oil (pareve) from a non ben yomo dairy frying pan directly from the flame into a fleishig sink. does the sink need to be kashered?
Thank you.
Answer:
No, everything is fine and there is no need for kashering.
The pareve oil, though cooked in a dairy pan cannot impart the "dairy" taste to the sink - certainly so where the pan is not ben-yomo and cannot impart any taste in the first place.
Best wishes.
