The rich flavours of juicy duck are balanced perfectly in this dish by the refreshing bite of citrus. Although simple to prepare, this wonderful meal is worthy of special occasions.
Using a vegetable peeler, peel the rind from one orange and one grapefruit, avoiding the white pith. If there is any pith on the underside of the peel, remove it with a sharp knife to leave only the coloured rind. Cut the rind into very fine shreds and place in a pan with enough cold water to cover well. Bring to the boil, reduce the heat and simmer for 1 minute. Drain.
