Cook the rice in boiling salted water for about 20 minutes. In the meantime chop peanuts coarsely. Peel the banana and wrap it with the cooked ham. Fry briefly in hot oil in a pan all around, remove and keep warm.
Peel and finely dice the onion and sauté in the frying fat until transparent. Stir in stock and cream and thicken as desired with a little sauce thickener. Season to taste with salt, pepper and curry. Wash the coriander, dab dry (put something aside for garnishing) and chop.
Drain the rice and mix with peanuts and herbs. Halve the banana and arrange on the rice covered with sauce.
