While the rice is cooking, clean, remove the stalk and quarter the mushrooms. Fry the mushrooms in oil and dust with curry. Pour in the cream and pineapple juice and add the stock powder. Season the sauce with pepper and chilli powder and simmer for a few minutes, then let cool.
Now mix the rice with the fruit, the meat and the prawns, pour the cooled mushroom-curry sauce over it and add the yoghurt or quark. Mix everything together well and season again with pepper, curry and chilli.
