Place the rice in a pan, cover the rice with water and bring to the boil.
Add 3 pieces of roughly chopped galangal and the salt to the rice. Cook the rice according to the pack instructions. When the rice is cooked, run under hot water and then under cold water to refresh the rice.
Remove the galangal, place the rice into a clean bowl and add the remaining ingredients and add seasoning to taste. Grate the remaining piece of galangal and squeeze the juice over the rice.
