Season the chicken with salt and pepper to taste. Heat the oil and 15 g (1/2 oz) 1 tablespoon of the butter in a large frying pan (skillet). Add the chicken and fry for 4 - 5 minutes on each side until lightly golden. Remove from the pan using a slotted spoon.

Toss the onion in the lemon juice, and add to the frying pan (skillet). Gently fry, stirring, for 3 - 4 minutes until just beginning to soften.

Return the chicken to the pan. Pour in the wine and stock, bring to the boil, cover and simmer gently for 30 minutes.

Remove the chicken from the pan, reserving the cooking juices, and keep warm. Bring the juices to the boil, and boil rapidly for 5 minutes.

Blend the remaining butter with the flour to form a paste. Reduce the juices to a simmer and spoon the paste

into the frying pan (skillet), stirring until thickened.

Adjust the seasoning according to taste, stir in the artichoke hearts and cook for a further 2 minutes. Pour the mixture over the chicken and garnish with chopped parsley.
