Ingredients
Directions
Heat the butter in a saucepan.
Add the sliced onion and carrot, and fry until browned.
Stir in the curry powder and flour, then add the water.
Remove the best parts of the fowl from the bones and set aside; add the bones to the stock along with the Liebig’s Extract of Meat and coconut.
Simmer slowly for 2 hours, then pass through a wire sieve.
Return the liquid to the pan, add the pieces of fowl and lemon juice, reheat, and season to taste with salt.
Serve with boiled rice.
