Sweet Saradomin on High, why on earth are you braising an undead eel? Are you a mind rune short of a rune pouch?
Perhaps it's a dare, and you're going to get a hefty payout after making it? I can't think of any other reason, sane or otherwise, why you would fish for the horrible, wriggly thing, pick it up afterwards, then braise it, which - we may add - is a process to DRAW OUT FLAVOURS.
What next? Bury it in the ground for days and eat it afterwards? I would not put it past you.
