Thank you NanaandGrampy! I will search for it online, I did see it at Morrisons, how odd it has gone so quickly and the label removed.
I've bought a Devil mix and will do as you suggest GabriellaG54, thank you. I had a look at Mary Berry's recipe and it's too fiddly, I'm really short of time at the moment.
