My daughter dropped a fish patty (that was fried on the dairy stove) onto a meat countertop. The patty had onions in it. The pot contained no milk when it was fried and wasn’t in use in a long time. The knife with which I cut the onions came from the dairy sink and might have touched a knife that was used for butter. The patty was hottish warm at the time that she dropped it on the meat counter. Is there any concern here considering the fact that the patty contained potentially dairy onions? (because knife came from sink).
No, there is no concern in this matter, and everything is fine.
The fact that the knife was in a dairy sink does not make it dairy, and the concern that it touched another knife is not sufficient to consider it dairy.
