Yes, they're supposed to be leaves people.
I debated about what kind of pastry to make (shortening - is it butter or copha? Apparently the answer is Crisco which is an American thing, not available on the shelves in Australia). In the end I went with Rees' recipe which you can find here. I used copha instead of Crisco.
I think next time though, I will use butter. The texture of the pastry was fine, nice and flaky, but the actual pastry (not the whole pie) was quite tasteless I thought.
