Instructions

  1. In a medium saucepan, bring vinegar, brown sugar, and garlic to a low boil, whisking until brown sugar has completely dissolved.
  2. Boil, stirring often until liquid has reduced by half; liquid will be a syrup at this point.
  3. Lower heat to a simmer and whisk in the beef broth. Whisk in the tamarind paste. Stir in the ginger and simmer to let sauce reduce a little more.
  4. Pour sauce through a sieve into a serving bowl.
  5. Spoon over sliced pork tenderloin.
