Here in NZ we have a little green pumpkin called a buttercup (not butternut - that's a yellow thing with a long stalk). The orange and grey pumpkins here are usually tasteless, watery and boring but the little green one is dry, sweet and almost chestnut flavoured.
Kiwis don't usually cook/eat pumpkin pie but I discovered it years ago and will often make it for a special occasion. People always enjoy my pumpkin pies - basically a similar recipe to those above - a spicy egg custard pie with cooked buttercup pumpkin in it for colour and flavour.
Pumpkin scones are good too!
