A true Pacific Northwest heirloom, introduced by Portland's Gill Brothers Seed Company in 1947. Beneath that beautiful blue-grey skin is thick, deep-orange flesh that's sweet, dry and fine-grained, with a flavor somewhere between squash and sweet potato. Even better, it improves with a little time in storage. Roast it, mash it with plenty of butter, turn it into soup, or use it for an exceptionally good pie.
