Everything went pretty well with the mash. I ended up mixing the pumpkin in the strike water, and then adding that to the mash. Opted not to use rice hulls, and nearly had a stuck mash... lesson learned.
Added powdered ginger, cinnamon, and nutmeg at 5 minutes to go, and then added vanilla extract in the secondary.
Other than some haze, I'm really pleased with this beer. Will probably do it again!
Thanks for all your advise and help!
