You could always use a small saw like this. Just keep it as one of your cooking utensils.
Yep, that's what I used last try
Are you cooking the pumpkin to eat, or for halloween decorations?
To make puree for baking
Dumb question, but, why not just stab it several times before baking. That's what we do to acorn squash and then we gut it after cooking.
Seems it would take hours to bake if whole.
If you do NOT "stab" around evenly around the pumpkin....the pumpkin may EXPLODE...or NOT cook evenly. Aria
Thought about microwave, but if it were to explode may have to buy a new appliance Wonder if there is a different flavor when it is roasted?
