My buddy and I had Aile de Raie for dinner last night. I think poached, with a nice sauce. (Our wives had pork osso buco.)
Have you ever caught a Skate? I've caught a couple over the years on Cape Cod while fishing for Stripers. Released them. Felt like you hooked a log. Should have cooked them.
I've had Joue de Raie once, years ago in France. Like a scallop. The "wings" are the more usual menu thing. A nice sweet white meat, and a first time for me.
Everybody who visits Atlantic beaches has seen their blackened egg cases ("mermaid purses") washed up. Skates lay those egg sacks, while Sting Rays bear live young. People eat Sting Rays, but do not step on one.
