Cut smoked duck into 12 thin slices. Cut spring onion into short lengths.

Place one sheet of spring roll pastry onto a flat surface. Brush egg wash all over the sheet. Paste another sheet on top. Add a slice of smoked duck and a spring onion in the middle. Brush egg wash around the edges, and wrap pastry around duck.

In a pot of hot oil, deep fry duck pastry until golden brown. Remove and cut into half. Serve.
