Lamb in tamarind and green chilli

My inspiration for this dish was sambal kambing goreng, fried lamb chops with green chillies, which I had years ago at Melur – a Malay restaurant in an Edgware Road basement (London) run by Pak Awie and his family, who used to run Malaysia Hall Canteen in Bayswater. It is one of those dishes that lingers in my memory, it was that good!
