Bastardized Tamarind Recado

Now... to say that this is a bastardized recado is probably putting it quite kindly. Honestly, this probably only merely resembles a recado if you were to tilt your head and squint at it. However, you can't fault where you find your ideas and I found this after becoming newly fascinated with tamarind but not quite sure what to do with it.

As such, into Epicurious, I typed "tamarind," hit enter and hoped for inspiration. It yielded this.

I should probably further qualify this recipe in that I just returned from a week in Mexico, followed by a flight delay in San Fran, an unexpected overnight stay, a reroute through Denver and a happy return home about 16 hours later than anticipated. Consequently, I had no groceries. At least nothing fresh (as sourly evidenced by the bit of buttermilk that I forgot about but was promptly reminded of when I opened the fridge to assess the situation). I also had no energy for a trip to the store but had *brilliantly* invited my Mom for dinner. All that aside, I do have a reasonably stocked pantry and a too full freezer... out comes a pork tenderloin and a can of crushed tomatoes.
