Several times I've seen recipes from the United States that call for canned pumpkin which isn't widely available in Australia. From research I see fresh butternut pumpkin / squash which is available should be a good substitute but I've found conflicting ideas on the best consistency and cooking method and I've never eaten canned pumpkin for comparison.
If I was to say halve a butternut pumpkin, remove the seeds and roast until it was easy to scoop out the flesh with a fork would that be a good substitute? I'm unclear as to whether boiling or roasting would be best, whether it should be puréed or somewhat chunky and if any other additional ingredients are required to best imitate the flavour of canned pumpkin?
