We eat gefilte fish at least twice, and sometimes three times on Shabbos (Sabbath). Many years ago, I found a need to find ways to make it a little bit differently. I started baking it, then I made patties, then I served it in a sauce and now I am making a completely different kind of patty.
The original recipe from Kosher by Design, Cooking Coach calls it a faux crab cake and uses surimi imitation crab. I could see no reason to do that. I wanted gefilte fish.
