Thanks for starting this thread, Badger! I'm looking for a good low-carb yam recipe...and one for cheesecake, as well....
A low carb yam recipe? LOL! Good luck.... :-)
Since you mentioned cheesecake, I'll add a little aside which isn't what you asked for ...
Cheap cheesecake thrill ... Kraft's Philadelphia Brand makes a ready-made cheesecake filling now, which can be found in the same dairy section with the regular cream cheese. Comes in a plastic tub. It's not bad for ready-made - you're supposed to just put it in a graham cracker crust and then garnish however you like.
Dreyer's Ice Cream has a "special limited edition" Pumpkin Ice Cream that they stock for a few weeks this time of year and I really like it. I mixed some with the Philly cheesecake filling and it makes a very easy, quick, luscious Pumpkin Cheesecake.
