Prepare the pumpkin for baking. Cut the stem off of the pumpkin to create a flat surface. Flip the pumpkin onto its flat edge and cut the pumpkin in half vertically. Scoop the guts out, optionally reserving seeds for snacking.
1-2 Pie pumpkins
Bake the pumpkin. Place the pumpkin halves face-down on a baking sheet and bake at 350 degrees F for 45 minutes or so. When poked with a spoon, the skin of the pumpkin should dent in, and return to its normal shape when the spoon is removed. LET THE PUMPKIN COOL.
Peel the pumpkin and place the meat of the pumpkin in a blender or food processor. Puree until smooth. If necessary, add water to thin the mixture and allow it to blend smoothly.
Water
Use or store your pumpkin puree. It can keep in the refrigerator for up to a week, or frozen for up to 6 months.
