Here's a comparison of the flesh color and thickness. The lighting wasn't very good so they all look a little bleached out. Note the thick flesh, I'd mentioned on number 6.
My favorite overall is number 1. Stark white skin (which came from 'White Scallop' squash) and yellowish flesh. High count of plump little hulless seeds.
Number 5 looks a lot like the 'Styrian Hulless' ancestor. It also has a serious flaw. The seeds have a strong tendency to sprout while still inside the pumpkin. This is something I've been selecting against, so I'll most likely never plant any seeds from this one.
Number 6 with its interesting thick flesh. I should've known by how heavy this guy was! This is a trait I'd like to keep in the population. So since it also has a high number of plump seeds, I'll probably use this one in the future plantings.
I don't generally follow any recipe anymore when I make bread, but this is essentially just white bread made with pumpkin puree in place of the water.
