Sri Lankan Fish Curry

Pour the water for the rice (amount specified in the ingredient list) into a large saucepan with half the vegetable stock pot and the cardamom pods. Bring to the boil, stir to dissolve the stock pot and add the basmati rice. Bring back to the boil, cover with a lid and cook on medium-low heat for 10 mins.Then remove from the heat and set aside for another 10 mins. TIP: The rice will finish cooking in its own steam.

Meanwhile, halve, peel and chop the onion into roughly 1cm pieces. Peel and grate the garlic (or use a garlic press). Trim the tops from the green beans and chop them into thirds.

Heat a drizzle of oil in a frying pan on medium heat and add the black mustard seeds. TIP: If you leave the mustard seeds for too long on their own they’ll start jumping out of the pan, so make sure you keep an eye on them! Once they begin to pop, add the onion and lime zest. Cook on low heat until the onion is soft, 5 mins, then add the Sri Lankan curry powder and garlic. Cook for 1 minute more.

Pour the coconut milk and the water (amount specified in the ingredient list) into your pan. Add the remaining vegetable stock pot and the green beans. Stir everything together. Simmer gently for 2-3 mins.
