Glad to help - had a thought that you could marinade the lamb in a mix of the same recipe spices for duck, such as -
2 tbsp five-spice powder
65g/2�oz sichuan peppercorns
25g/1oz whole black peppercorns
3 tbsp cumin seeds - whole
200g/7oz rock salt
Wrap in c/film and leave for at least 24 hrs. There are variations but thi is about the basic mix...
Shred the lamb finely, dust in cornflour and fry to get the crispy finish - this should be close to the crispy duck style dish. A more crispy finish will come from mixing cornslour with a pinch of salt in some egg white - douse the lamb shreds in this then deep fry to finish....
Last idea which would work too - shred the lamb meat, dip in a mix of cornflour and soy sauce. Deep fry, remove from oil when done and sprinkle with more cornflour - fry again to colour the flour - serve in pancakes......
Bon appetit!
