Very good and easy to make.

There are some errors in the recipe, but nothing too major.
- Dice the potatoes into 2cm (1/4in) cubes ... probably should be 3/4in. The picture clarifies.
- My 2cm-ish cubes took much more than 6 minutes to cook. Maybe 10 or so.

I made a half recipe as a large side dish for two.

I forgot to start this early to allow time for 60min simmering. Oops. But I remembered that in Quick and Easy Indian Cooking, Jaffrey gives the option of simmering a dish for 60min or pressure cooking it for 20min (with less liquid). So I did that instead. Resulting in very tender pork in a yummy sauce.
I bought some organic tomatoes that turned out to be tasteless, so I'm sure this would be even better with proper tomatoes.
