One of my all time favourite and my mum's too. I was over the moon when I saw them sitting in a frozen food specialist in Chinatown. Retailing at £6.80 per packet, it is not cheap.
Preparing the eel is easy, the instruction said just boil the packet in boiling water. I took the pack out of the freezer and let it thaw for about 10 minutes or until the fish can come off easily and does not stick to the inside walls of the plastic packet. Cut open and take half a portion put it on foil and grill it in the oven for 5 to 10 minutes, skin side up.
Serve it on bed of rice and Japanese style dashi stock sauce.
The other half of eel, I used it in fried rice.
