Yup, bake the pumpkin, steep it with grains... heck, I even added it to my boil for a while. Add the spices near the end of the boil. (I added mine at about 10 min). I removed the pumpkin prior to adding spices so the spices didn't get caught up in the grain bag I used to hold the pumpkin pieces. However, the hops got caught up in the pumpkin; made the best darned pumpkin pie I ever tasted!
