Hmmmm difficult question to answer as I love both. Love pumpkin a little bit more though. I love roast pumpkin, pumpkin soup, pumpkin scones, pumpkin and fruit cake.... But then I also love grated raw carrots, cooked carrots, roast carrots, carrots in soup, carrot cake, carrot and sultana muffins.
We have both pumpkins and butternut squash. For us, pumpkins are the round fruits used for halloween, whereas butternut squash is the long fruit. Which one are you referring to? I like both as they are both part of the same smily and have a similar flavour, but I do prefer butternut squash. In fact, it is one of my favourites, despite the fact that I don't eat it very often.
