My pastry only stretched to 19. The blessed Saint Delia said I should have made 3 dozen?!!! That's 36 the last time I worked it out. How?! I used the right sized cutters, and perfectly normal patty tins.
Impossible.
And the raw pastry, which I normally love, tasted really boring. So much for lard and butter. 
God bless Mr Waitrose and his ready rolled stuff. Cos that's where I'm heading with the next lot.
Meanwhile, back to the original question.
