Tried the ricer with the apples last night, and, well, it didn't work that well. Perhaps the apples were too small and didn't allow me to get enough torque on the handles. I popped in a few slices and only a trickle of apple juice came out. So I threw them in my Magic Bullet instead.
The curry came out great, though. These days, I start with mirepoix and sweat it in the pan, like I were starting a sauce. I added the apples with water and reduced, then added white chicken stock and reduced again. I strained that and used the resulting sauce as the liquid base for the curry. The result: just the right hint of appley sweetness.
