The first thing you do it cut it up into wedges, removing the stem, and any bad pieces you find. You have to scrape out the seeds and all that, and if yo have made a display pumpkin, this has already been done, but if you haven’t…. well, I have taken to leaving the pumpkin out in the snowbank to freeze. Then I go at it with a hand saw (I clean it first). It is surprisingly easy to cut, the slimy seeds in the center are much easier to scoop out frozen, and it leaves your snowbank looking a little bit like a pumpkin slaughter-house until the next snowfall.
