Pork in a Mustard Spice Mix

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.
