I seem to recall an early series of Huge Fearlessly-Eatsitall bobbing around the canal system in a boat called the Bain-Marie, and foraging a bit. He then tried to get Joe Public to try the things he cooked.

Sorrel from the tow-path where folks walk their dogs, and inflicting woodlouse omelette on some poor unsuspecting chap who was passing by with his little lad (who tried manfully to be polite and say it was OK, but whose face told another tale) are two episodes I remember.

The whole thing was a bit crazy, maybe Parry would have a different take.
