For the fish with mango-pineapple sauce, first peel the mango and cut the flesh into rough cubes. Then peel half the pineapple and cut the flesh into small cubes.
Now fry the fruits in some oil and season with garlic, soy sauce, bouillon cubes and curry powder. Let fry for a few minutes and then add a dash of water (until the fruits are just covered).
Simmer for a few minutes, stirring in the curry paste. When the fruits are soft-boiled, finely puree with a blender and pour in the coconut milk and continue to simmer.
Finally, add salt to taste and season with the other spices if desired. For the fish, mix the flour with the herbs.
Salt the fish a little and dredge it in the flour mixture on both sides. Heat some oil in a frying pan and brown the fish well on both sides.
While the fish is frying in the pan, cook the rice well in plenty of water.
