  This Singapore dish is a classic and, like all classics, it is superb.
  Serve it with plain rice.
  Boil a large pot of water and drop in 4 green blue swimmers. Boil them
  rapidly for 4 minutes then tip the contents of the pot into a colander to
  drain. When cool enough to handle, chop crabs into quarters with a cleaver
  or large knife, leaving legs at- tached to body. With a hammer. gently
  crack the claws and areas of harder shell.
  Put 3 teaspoons tamarind pulp to soak in 3/4 cup boiling water. Finely chop
  2 onions, grate 5 cm piece fresh ginger, finely slice 2-3 birdseye chillies
  (or to taste) and chop 3 green (spring) onions. Mix 2 teaspoons cornflour
  with a little water.
  In a large wok or pan, heat 3 tablespoons of oil and stir- fry onion,
  ginger and 2/3 of the chopped chillies for a couple of minutes. Add crab
  pieces and strained tamarind water, lower heat and simmer for 3-4 minutes.
  Lift the crab out onto a serving dish and to the mixture in the wok add 3
  teaspoons sugar and 2 of tomato paste. Stir, add dissolved cornflour and
  stir again until the mixture thickens. Pour over the crab, garnish with the
  rest of the chillies and the spring onions and serve.
