I live in England and we don't use pumpkins very much at all, basically they're in the shops for a couple of weeks around Halloween and that's it, and it's pretty much impossible to buy canned pumpkin puree here, so I boiled the pumpkin and then liquidised it to make the puree, and I had to make a few other substitutions for things I didn't have - I used
creme fraiche instead of yogurt, dark brown sugar instead of light, and cake flour doesn't exist here so I just used
plain white flour.
