Peel ginger and garlic and dice finely. Cut the chilli lengthwise. Scrape out the seeds and chop finely. Wash chicken fillets and dab dry. Heat clarified butter in a pan.
Fry the chicken fillets in it all around for about 10 minutes. Remove and keep warm. Add curry paste, ginger, garlic and chilli to the frying fat and sweat it on. Dust with flour and sweat it on. Deglaze with stock and coconut milk while stirring.
Cut the fillets into slices and add to the sauce. Add the peas to the sauce without defrosting and bring to the boil again. Drain mango and cut into cubes. Pour into the sauce and heat it up. Wash the coriander, dab dry, pluck the leaves from the stalks and chop finely.
Add to the sauce and fold in. Arrange everything together and garnish with chilli cut into fine rings if necessary. Pappadums (Indian thin chip-like pastry made of lentil flour) are delicious with it.
