Okay, I just went to order whitefish, pike and carp for gefilte fish (mom's "recipe") and was told by my fishmonger that here in NYC, it's virtually impossible to get whitefish this year due to the obscenely cold winter resulting in whatever lake they get the fish from still being frozen over. My guess is that if I searched high and low for the next two days, or went to a high-end Manhattan fish store, I might get lucky and someone might have it, but I don't have the time to do that.
(1) Has anyone else been told this story about a whitefish shortage? I've only found one story about it on the internet and it's about Chicago, not NYC.
(2) What's a good substitute for whitefish? I'm not a big fish-eater, so I really don't know what's at least passingly similar to whitefish in taste. The fishmonger says people are using striped bass as a substitute.
