Cut the duck into serving size pieces. Reserve 30
ml/2 tbsp of corn-flour and coat the duck in the
remaining corn-flour. Dust off the excess.
Heat the
oil and fry the garlic and duck until lightly
browned. Remove from the pan and drain on kitchen
paper.
Place the duck in a large pan. Mix together
the wine or sherry, 15 ml/1 tbsp of soy sauce and
the ginger.
Add to the pan and cook over a high heat
for 2 minutes. Add half the stock, bring to the
boil, cover and simmer for about 1 hour until the
duck is tender.
Meanwhile, soak the mushrooms in warm water for 30
minutes then drain. Discard the stalks and slice the
caps.
Add the mushrooms, bamboo shoots and water
chestnuts to the duck and cook, stirring frequently,
for 5 minutes. Skim off any fat from the liquid.
Blend the remaining stock, corn-flour and soy sauce
with the sugar and pepper and stir into the pan.
Bring to the boil, stirring, then simmer for about 5
minutes until the sauce thickens. Transfer to a
warmed serving bowl and serve garnished with spring
onions.
