Heat the oil in a large wok or heavy-based frying pan and cook the onion, garlic and ginger over a gentle heat for 8 minutes. Add the curry leaves, cardamom pods, lemongrass, spices, pepper and half of the green chilli and cook for 5 minutes.
Add the coconut cream, stock, fish sauce and lime leaves, bring to a boil then reduce the heat to a simmer for 15 minutes. Add the prawns and beans and cook for 8-10 minutes until the prawns are cooked through. Squeeze over the lime juice from the lime halves, garnish with the remaining green chilli and serve immediately with steamed rice.
