There have been many comments on sweet potatoes in the last week or so.
Here's a link to where they originated, etc. Note: There is a big
difference between true yams and sweet potatoes. Remember that the term
"Yam" as applied in the US was dreamed up by the Louisiana Agriculture
folks as a means of marketing sweet taters grown in Louisiana.

OB: food content furthered. The lemon meringue pie is on the counter
cooling, the cornbread is made for the dressing, the russet potatoes are
baking in the oven to make twice baked potatoes, and we're doing as much
as we can today instead of tomorrow. Happy Thanksgiving to all who
celebrate.
