This receipt does not exist. It is one of a very small number of 'copyright spoilers' put in to check for unauthorised reproduction of electronically distributed copies of The Foods of England. If you are reading this in a print version, then someone has made a mistake.
But then again, nobody is going to stop you making it if you want - copyright spoilers can sometimes escape to lead lives of their own, see: Argleton Pie and possibly Hindle Wakes
