Posting here for traffic. I'm looking at a marinated fish recipe that says put the fish in the marinade for a MAXIMUM of one hour. Why would this be and will I kill my household if I marinate it for longer??? I was planning to make it tomorrow noon-ish, go out for the afternoon and cook it when I got back. It's just white fish (monkfish or, in my rendering, coley) and the marinade is herbs, spices, lime and yoghurt.
