I just had some grilled skate wing. Bought fresh from the supermarket
and grilled at home.
It had a strong smell of ammonia.
I have just learnt that Skate are a member of the Shark family.
Shark and Skate urinate through their skin hence the smell.

Has anyone else heard of this?

than grill them. Could that make a difference?
I poach them, drain them, and then place on a plate. Then fry butter
until nut brown, splash in some wine vinegar and capers all of which
gets poured over the skate wings. Great with small, very yellow, waxy
potatoes.

Then again I enjoy kidneys so perhaps I'm the wrong person to respond.

I stopped buying skate a very long time ago because of the smell and I can't
see anything persuading me to buy it again.
