Karen, I am not sure what they did. Only thing I can think of is that I baked my potatoes...
because I was worried if I boiled them there would be too much moisture. I was surprised at the lack of directions for a Martha Stewart recipe. Her recipes are usually much more specific. Also, I don't have any pumpkin pie spice so I used my own mix of cinnamon, cloves, ginger and allspice. I doubt that would have any thing to do with the gummy bear texture. DH and I are both enjoying it and he asked if I would make another when this one is gone!
Only thing I would do a bit differently is to put more pecans in the pan, make sure more stick to the sides as well as on the bottom. And I might add the zest of an orange just to see what that might add--or not!!
