In my school days, if there was one thing you had to watch for on April 1st, it was paper fishes hanging on your back.
A harmless joke called Poisson d'Avril.
French chocolatier Patrick Roger who can be mischievous turned the tradition into an edible fish, a praline cookie covered with a thin layer of dark chocolate.
Give me a dozen of these to munch on.
Happy April Fool's Day!
