Given the popularity of sushi at the fanciest simchas, it was only a matter of time before someone attempted to formalise the special relationship Jews have with the Japanese rice and fish snack.

There's been smoked salmon and cream cheese sushi and herring sushi, but the latest creation is a sushi-shaped mezuzah - a picture of which was circulated by Rabbi Rashi Simon from educational group Kesher.

Might be difficult to nail to the door post.
