Does anyone know the man in the white hat who struck a rare blow for kashrut on TV?

Put anyone Jewish on a food show and you'll usually see them scoffing shrimp, eel, lobster, pig's ear, pig's foot, pig's unmentionable or other piece of Shulchan Aruch-defying creature.

But when this market stallholder was invited, in this week's Heston's Feasts on Channel 4, to sample Heston Blumenthal's jazzed-up spam dish, he replied: "I am not allowed to eat that, I'm Jewish."

Is he a genuine, abstemious member of the tribe - or was he just having us on?

Meanwhile, talking of Jewish food, Gwyneth Paltrow was raving the other day about Claudia Roden's "brilliant" Pesach recipes.
