Inspired by this thread, I made fish cakes for the first time. But, forewarned by this thread, I ignored all of the fish cake recipes. I based mine loosely on swedish fish balls - chopped rockfish, breadcrumbs, egg, old bay. I did not poach the fish, but just mixed it raw with the other ingredients and let the breadcrumbs bind everything together. Saute in patty shapes for about 3-4 minutes per side, and I was happy with the results.
My wife called the mayonnaise / mustard / tarragon sauce I made “zippy”.
