Heat a pan of water until boiling. Tip in the broccoli and cook for just 1 min – it should still have a good crunch. Meanwhile, mix the stem ginger and syrup, soy sauce, garlic and finely chopped chilli.

Toast the sesame seeds in a dry wok or large frying pan. When they’re nicely browned, turn up the heat and add the oil, prawns and cooked broccoli. Stir-fry for a few mins until the prawns turn pink. Pour over the ginger sauce, then tip in the beansprouts. Cook for 30 seconds, or until the beansprouts are heated thoroughly, adding a splash more soy or ginger syrup, if you like. Scatter with the sliced chilli and serve over rice or noodles.
