6 Add prawns
Add the prawns (see pro tip) and the soy sauce. Bring to a boil and cook for 3 min further or until the prawns have cooked through (do not overcook or they may become rubbery). Check the seasoning. Divide the soup among bowls. Garnish with a swirl of reserved coconut milk. Top with the sliced sugar snap peas, red chilli (spicy!), lime wedges and chopped coriander.
