I attended a wedding anniversary party at Cafe Juanita and one of the dishes served was Fried Asuhos with crab fat. I'm not really a fish person, though i enjoyed eating this, though i'm not sure if it's because of the crab fat. ;)
Seeing some frozen Asuhos at Cold Storage in Rustan's Supermarket, i decided to do it myself, without the crab fat. I seasoned it with salt and pepper, some freshly squeezed lemon then covered it in flour, eggs and japanese bread crumbs.
We had this for dinner and was good even without the crab fat. Ketchup or pickled mayo will do.
