Bring a large pot of water to a rapid boil with a pinch of salt. Wash the rice under running water for 30 seconds (important step!). Add the rice to the boiling water and boil for 25 mins until soft enough to eat. When the rice is cooked, drain it, put it back in the pot off the heat and cover with a tea towel.

Meanwhile, peel and roughly chop the onion and peel and finely chop the garlic. Peel the ginger using the edge of a spoon and finely chop. Cut the very top and bottom off the green beans (i.e. ‘top and tail’ them) then chop them into three pieces. Wash the sweet potato and chop into 1cm cubes, then roughly chop the coriander. Tip: No need to peel the sweet potato as the skin is very nutritious!

Heat a frying pan with a splash of olive oil over medium heat. Add your onion and cook for 4 mins until soft, then add your garlic and ginger and cook for another minute. Add the Sri Lankan curry powder, sweet potato, as much of the chilli flakes as you dare, along with a pinch of salt and mix well.

Add the coconut milk. Refill the tin halfway with water, swill it around and add this too. Cover with a lid and cook gently for 10-15 mins, until your potatoes are just cooked. Add your green beans and continue to cook for a further 5 mins.

Toast the cashew nuts in a dry frying pan for a few mins. Watch them carefully as they can burn quickly. Once your cashews start to brown, add the desiccated coconut. Tip: Be careful as the coconut can burn really quickly too.

Once your sauce has bubbled down to a nice thick consistency, squeeze a little your lime juice into your curry. Stir through three-quarters of your coriander. Add more salt and black pepper to taste.

Serve your rice topped with your curry, your toasted coconut and cashew and your remaining chopped coriander.
