I kept leftover salmon skin when I made fall salmon doria, and turned it into chips as a topping It doesn't smell. It's fragrant and delicious!!
I often have a salad with fried onions on top, and I got a hint from it. I used fried salmon skin instead.
The oil spits when frying the salmon skin.If you're afraid of that, it's better to coat the skin with cake flour.
Enjoy Japanese food around the world.
