Okay, no word of lie, this is pretty damn good pie. The filling is a delicious mix of smoky, spicy and sweet, topped with just enough pastry to make it seem a little sinful, but not enough to make it that sinful, really. It's a great pie to make for dinner guests, or you might just make for a family dinner. Or do what I did, make for guests that can't make it to dinner, and then plan to eat it all yourself!
Normally I'm not a recipe fascist, by any means. I often say substitute and swap ingredients as much as you need, or within reason. But for this pie, if you really want the experience I just had in eating it - then you have to do as the recipe says - at least for the flavourings/spices. The smoked paprika is very essential to this working. Don't use standard paprika - go buy some smoked. It's available in Asda and Morrisons and wherever, so do make sure to get that in.
