Clean the crabs by lifting the small flap underneath and removing the shell.
Pull of the gills underneath, and rinse away all the innards. Cut in half through the body, leaving the legs attached. Crush the claws slightly so the flavours can penetrate to the meat
Heat the oil in a very large wok. Add the lemon grass, ginger, and garlic. Fry for about 2 minutes, until fragrant. Add your crabs and a little water, cover and steam.
Add the cubed mango, sweet chilli sauce (good quality). Add the deseeded chillies and stir to combine. Keep coating the crab with the sauce, to ensure flavour.
Serve in a bowl, topped with fresh coriander and a squeeze of lime.
Matthew is ever so handsome.
