Place the skinned
raw breast of duck on a board and hold it in
position with one hand while cutting it diagonally
into thin slices with the other.
Work the
bicarbonate of soda into them and leave to rest for
at least 1 hour. (Duck is a firm meat. The effect of
the soda on it is to tenderize it.) Cut the ginger
into thin strips and the onions into 2-inch lengths.
Work the
seasonings and 2 teaspoons sherry into the duck.
Heat the oil in a frying pan.
Add the duck and toss
it while cooking for 3 minutes. Add the ginger and
onions and cook for another 2 minutes. Add the hot
stock and the remaining ginger sherry. Bring to the
boil.
Stir in the
corn-flour, blended with the water, and boil for 1
1/2
minutes. Turn into a heated dish and serve.
