The Perfect Hamburger

¿That,¿ said Mr Borthwick, ¿was the best hamburger I¿ve ever tasted!¿

Joe has just created the yummiest, juciest, most delicious hamburger ever ¿ and his friend Mr Borthwick wants to sell it in his new hamburger shop. But there¿s a problem ¿ Joe has completely forgotten the recipe and the shop is opening very soon.

A pinch of this, a touch of that and a spoonful of something else¿the race is on for Joe to remember!
