OK, so after a couple seasons of failed attempts (yes, you were right jal_ut! ) I've decided it's just too difficult, especially in my small garden, to try to save pumpkin and squash seeds from year to year for growing.
(yes, last resort would be to bag/tape closed the blossoms and hand-pollinate, but I'm not up to the extra task and would much rather see bees taking pollen baths in them )
So, of all those seeds -- WHICH tend to be good to eat? Are any large and worth cracking seeds edible? Are gourd (C. pepo) seeds edible too? -- Birdhouse and Bushel gourd seeds look completely different so I'm not really sure about those.
I just prepped a Spaghetti squash (C. pepo) for dinner, and it had meaty looking seeds just like pumpkins. So it was raw, but I cracked one open and tried it and it was pretty decent. Not as nutty maybe, but that might have been because it was fresh out of the fruit.
I had a store-bought small squash -- not delicata, but similar creamy color with orange stripes, shape was squat and lobed -- last week. This one had small seeds, but I dried them anyway, and I tried it just now. The seeds seemed almost too small to bother, but the flavor was outstanding... maybe worth the effort.
