Wash, clean and chop the spring onions. Halve 1 chilli pepper lengthwise, remove seeds. Cut the pod into small pieces. Wash coriander, shake dry and chop coarsely. Prepare rice in boiling salted water according to package instructions.
Dab meat dry and cut into thin strips. Boil up chilli, coconut milk, 100 ml milk and curry paste. Stir 50 ml milk and starch until smooth and thicken the coconut sauce with it. Simmer while stirring occasionally and season to taste with salt and some lime juice.
In the meantime, prick 1 chilli pepper several times with a knife. Heat the oil in a pan. Fry the meat strips and the chilli in it for 3 minutes, then add spring onions and season with salt and pepper.
After about 1 minute, add the meat, spring onions and 1/2 of the coriander to the hot sauce (do not bring to the boil again!). Drain the rice. Garnish with remaining coriander and serve with rice.
