2,359. Meat That Falls Into Milk (Or Vice Versa)
Maachalos Assuros 9:8
If meat falls into milk, or vice versa, and they’re cooked together, the minimum measure to incur liability is enough for one of them to impart flavor to the other. Therefore, if a piece of meat falls into a simmering pot of milk, a non-Jew should taste the milk; if it has the taste of meat, it’s prohibited. If not, the milk remains permitted but the meat that fell into it is prohibited. This is the case when one quickly removed the meat before it could discharge any milk that it might have absorbed; if he didn’t remove it right away, then we require that the milk be 60 times the volume of the meat because the milk that’s absorbed by the meat is rendered prohibited. It was expelled and mixed with the rest of the milk.

If milk falls onto meat in a pot, we have a non-Jew taste the piece of meat on which it fell. If it doesn’t have the taste of milk, everything is permitted. If the meat has the taste of milk - even if pressing the piece of meat would cause it to exude the absorbed milk so that no taste of it remains - it’s prohibited because it has the flavor of milk right now. We must therefore measure the entire volume of the food. If everything else in the pot, meaning other pieces of meat, vegetables, sauce and spices, is enough so that the one piece is 1/60 of the whole, then that piece is prohibited but the rest is permitted.
