I made this recipe for Rosh Hashana at a friend's request (made it for Passover earlier in the year) and it got rave reviews again. Real gefilte fish isn't possible in this town because the markets don't get the kind of white fish that's required. But everyone says they like this more.
It's a bit of dirty work to chop and grind the fish (especially for a vegetarian) but so worth it for the rave reviews. It does not make the gel that goes with boiling gefilte fish. We serve with the magic red horseradish sauce (that can only be purchased at one market here and therefore all the local Jews go nuts for).
I made it with 1# salmon, 1# halibut ($$), 1# cod (Last time I made it with 2# salmon, 1# halibut)
