That recipe sounds pretty yummy - I may try it myself...
As to the apple sauce - I\'m afraid I\'m too lazy to make it from scratch and just buy it ready in a can; it definitely is thick and rather plain tasting that\'s why the one in the recipe you directed me to sounds much better.
The one from a can looks and tastes similar to what you would get if you cooked some apple pieces (like when you make a fruit compote) and then mashed them.
