Yep, you can munch on most pumpkins, but not all are going to taste great. Some pumpkins are grown especially for eating, like sugar pumpkins, which are sweeter and less fibrous. Others, mainly those big ones carved during Halloween, might not be as tasty because they're bred for size and durability, not flavor. Always best to check if the pumpkin variety is good for cooking before you start baking a pie.
