“It details how a cook should use minced meat, pepper, pine nuts and a rich fish-based sauce and form them all into a patty shape.”
So it’s a combination Whopper and Whaler, hold the bun, Adkins-style.

I miss the old Whaler fish sandwiches from the ‘70s. They were big sandwiches, not like the little ones they offer now. I had a second job at BK in 1979, and ate a ton of them. Also made a few triple Whoppers. Too much! Burp!
