To make the crispy duck, dust the duck legs in the Chinese five-spice powder.
Bury the legs in the salt, weigh it down and chill in the fridge overnight.
Preheat the oven to 170C/150C Fan/Gas 3.
Rinse the legs and place in the duck fat with the spices, garlic, ginger and bay leaf. Cover everything with the fat.
Cook for 1½ hours and then leave to cool in the fat.
Increase the oven to 220C/200C Fan/Gas 7.
Cook the duck legs, skin-side down, in a hot frying pan.
Roast in the oven for 20 minutes until crispy.
Shred the duck with two forks or shred the duck and crisp up again in a frying pan. Set aside.
To make the plum sauce, place all of the ingredients and 5 tablespoons water in a saucepan.
Bring to the boil and simmer until all of the fruit has collapsed and reduced, this will take around 20 minutes.
Push through a sieve into a bowl and season with salt and pepper.
To serve, place the duck, sauce, cucumber, mooli and spring onion in the pancakes. Roll and enjoy.
