Preheat the oven to 400 degrees. Oil jelly roll pans with lots of oil, or a combination of shortening and flour (any kind of flour to form a oily paste). Smear it all around and set aside.

Wash and peel the yams.

Cut the yams into rough chunks so they fit into Cuisinart. You'll want to have the grater attachment set into the bowl. Use the wide mouthed chute for the potatoes.

Combine all remaining ingredients in a bowl and mix well. If it isn't totally smooth, forget about it...it'll mash up after you blend in the grated yams. Squish around until well mixed.

Scoop the yam mixture onto the prepared pan and flatten to form the latkes. Place pan into the hot oven and set a timer, watch them and otherwise don't let them torch in the heat! Depending on your oven, the time to cook will vary. Start with 8 - 10 minutes.

When a golden ring is forming around the edge and the bottoms are browned, flip and continue to cook. Feel free to add more oil if they need to 'fry' more. Remove from the oven when they are done and that's it! They can be refrigerated and heated in the oven or by pan-frying. This is a good way to make a show of frying latkes in real time without the hassle of actually cooking them.
