Since I'm sure you were wondering . . .
Yes, the manhole cover turned out to be fully edible. And yes, I made my mom's dressing recipe without incident. My dressing did taste slightly sweeter than hers - I probably screwed up the bread cubes to cornbread ratio somehow. I also used less pepper than she does because, to quote my mother: "Claudia thinks a mashed potato sandwich is too spicy." She has also been known to call me a "candy ass" because I'm not big on spicy foods. And keep in mind that I am her favorite!
The made-from-scratch cloverleaf rolls did cause me some angst in the afternoon when I began to fear that the yeast was not doing its job. The dough did not appear to be rising. However, eventually it thought better of becoming a failure and did what it was supposed to do. Homemade rolls are labor-intensive but oh so good. Carb heaven! The vegan gravy was pretty good. I can live without it but it wasn't bad.
My daughter helped with the mashed potatoes. And by "helping," of course I mean "caused the process to take ten times longer than it normally would." All in all, though, it was a very nice Thanksgiving at home, with just our little clan.
