  COVER tamarind PULP with 1/2 cup of boiling water. With the back of a fork,
  mash the fibers and seeds. When dissolved, strain, and reserve 1/3 cup of
  tamarind water. In a food processor or mortar, process or pound the
  shallots, garlic, chiles, shrimp paste, turmeric and salt into as smooth a
  paste as possible. Set a wok or skillet over medium-high heat. When hot,
  add the oil and spice paste; gently brown. Turn heat to high and add the
  shrimp; stir-fry until they turn bright orange, about 30 seconds. Remove
  and set aside. Add bell peppers, peas and cabbage; stir-fry until
  vegetables are cooked but still crisp, about 1 1/2 minutes. Add rice;
  stir-fry together, breaking up the lumps of rice. When the rice grains are
  separated, add tamarind water, ketjap manis, light soy sauce, green onions,
  chicken, barbecued pork and reserved shrimp; mix together. Check for
  seasonings. Transfer to a serving plate, garnish with coriander and arrange
  the cucumbers around the edge.
