Put the rice in cold salted water or water with instant stock, cover and simmer over a low heat. The rice is ready when there is no more liquid in the pan, it is not necessary to stir. I use Basmati and Thai rice 1: 1 for this.
In the meantime, heat the oil in a large pan, add the onion and leek, cut into strips, and let it translate. Then put the thawed broccoli in the pan, fry for 5 minutes, then deglaze with the cream and milk and season with salt and curry powder. Heat the chopped mango in the sauce and finally fold in the cooked rice.
