So Norther Brewer has pumpkin ale extract kit that is now headed my way. But the actual pumpkin flavoring is left to the brewer. I've read everything from cutting up pumpkin, boiling it and using the boiled flesh, to boiling and adding canned pumpkin purée. I had an idea of buying a large pumpkin, skinning it, cutting the flesh up in chunks, throwing it in the brew kettle with about 3-4 gallons of water and boiling for an hour. After which I would remove the pumpkin and brew using the "pumpkin broth if if you will. Ideas?
