Put rice in 100 ml boiling salted water, cover and let it swell for about 20 minutes at low heat. Peel the orange so that the white skin is completely removed. Use a sharp knife to cut out the flesh between the parting skins.
Press the remaining juice out of the separating skins and collect it. Clean, wash and cut the spring onion into rings. Wash chicken fillets, dab dry and cut into cubes. Heat oil in a pan.
Brown the chicken meat all around, dust with curry and deglaze with stock. Add spring onion, orange slices and orange juice to the pan and let everything simmer for about 5 minutes. Refine with crème fraîche and season with salt and curry.
Arrange on plates together with the drained rice and serve garnished with lemon balm.
