My sister decided to grow pie pumpkins this year so I started looking to see how to can it. They say not to pressure can puree but leave it in chunks instead. So what we might do is bake it, then scrape the innards and freeze it. My sister still has one of my butternut squash in her basement from last year and its still good so she wants to take all her many pumpkins down there and see how long they hold up so we won't have to do much to them till we want to use them. She made a meal with a stuffed pumpkin using veggies, rice and meat baked right in the shell of the pumpkin. It was very tasty.
