Tip the sugar into a wok, add a splash
of water and let it dissolve over a low heat.
Once dissolved, turn up the heat until it
bubbles, then pour into a heatproof bowl.
Heat the oil in the wok, then stir-fry the
broccoli and sweetcorn for 3 mins until they
start to blister. Stir the curry paste into the
caramel, then pour into the wok. Add the
pepper and continue to cook for 2 mins.
Splash in the fish sauce or soy, add the
prawns and fry again to heat through.
Serve immediately with rice or noodles.
