I cooked the squash and here is my report. The squash was easy enough to cut and the color was a lot like a butternut. I couldn't tell much about its texture until it was thoroughly cooked. And when it was, it was soft and perfect for soup. It did not have the intense sweetness or dense texture of my favorite squash which is the delicata. I am sure that I prefer a number of other squash over Aunt Thelma's Sweet Potato Pie squash. And when I make Sweet Potato pie, I prefer having sweet potatoes in it. It's one of two dessert recipes in my cookbook, The Veggie Queen: Vegetables Get the Royal Treatment.
Since I also really like squash soup, this squash was just fine. I liked the size of it but I'm not likely to buy one again. Good thing that I have a few delicata squash put away for future use.
