Here is how they came out.
Needless to say, they were delicious! Made with sweet potatoes (I used not too sweet yellow fleshed ones), ground almonds, and sugar, after being baked they wind up with a chewy consistency somewhat like marzipan. Although there are a couple of variations for finishing them, I coated mine with pine nuts before baking. Like gorkabear , I would probably make them a bit smaller the next time.
