give ya a good exampple of the "Less Desirables" would be certain Fish heads which come the right time of the year like winter in the hands of a wee bit of experience make some of the best Soup out an d a taste for some "TO Die For" lol.
The Occy for instance which is talked about under NoelM's post , whether be it baby occy or Humungas tentacles which can make some of the best Piccled or barbacued Occy and a something of a must around Greek Barby (If one can get their paws one one nowadays..
