Baker creek is one of the places I orderf rom every year. It's so hard to know the "good" squash varieties, nice to hear folks talking about their favorites. I'm always open to new varieties. I've already done my ordering from rareseeds this year unfortunately. I might have picked up this one.
I too love Baker This is my favorite squash http://rareseeds.com/seeds/Squash-Winter/Shishigatani-or-Toonas-Makino
The flavor is lovely and it keeps super well. I h ave one left from the harvest that has been on the counter all winter. It cooks well in soups and stews and doesn't tend to fall apart. It has a lovely sweet buttery flavor. The yeild isn't very high, but all its other qualities make up for it
