Instructions:

1. Wash the rice and soak in cold water overnight.

2. Drain the rice and place in a large saucepan. Add the cinnamon stick, cloves, cracked cardamom pods and a large pinch of salt. Cover the rice in plenty of water (as if you were boiling pasta) and bring to a boil. Because you soaked the rice it will take less than 5 minutes. Once the rice is 70% cooked, drain and set aside.

3. To make the buttermilk mushroom masala: wipe and slice your mixed mushrooms and set aside. Place the ghee in a large pan and allow to melt on a low heat. Add the cumin seeds, cashews, bay leaf and asafoetida. Once aromatic, add the ginger, chilli and onion. Sauté on a medium heat until the onion has caramelised. Add the tomatoes and cook until most of the water has evaporated.

4. Next, add the mushrooms and cook until the mushrooms have softened and reduced by half. Add the turmeric, season with salt. Cook for a further few minutes and then. Switch off the heat. Add the buttermilk and stir quickly to incorporate. Add the chopped tarragon and give the mushrooms a final stir.

5. Pre-heat the oven to 190°C.

6. Take a large, handi (you can also use a Dutch oven if you don’t have this). The most important thing is that it’s deep, ovenproof and has a lid. Grease with butter and place a layer of rice on top. (Note: I usually keep the cinnamon etc i boiled the rice with in and remove it before serving.) Cover the rice with a layer of mushroom mixture. Add another layer of rice and add some of the saffron milk, a drop of rose water and fried onions. Add a little more rice and repeat layering with mushrooms and rice until you run out. Finish with rice on top and repeat the saffron milk, rose water and fried onion layer.

7. Combine the flour and water and knead to make a firm dough. Roll the dough out into a long sausage shape and use it to line the rim of the biryani pot. Place the lid on top and bake for 35-40 minutes.

8. To make the raita: Slice the cucumber in half lengthwise and scrape out the seeds. Grate and squeeze out any excess water. Place into a large bowl. Grate the carrot and squeeze out excess water. Add the chopped herbs, chopped spring onion, lemon juice, salt, sugar and yogurt. Stir to combine.

9. Toast the cumin seeds in a dry frying pan and coarsely grind in a pestle and mortar. Add to the raita and stir. Top the raita with pomegranate seeds. Chill until ready to serve.

10. Take everything to the table and open up the biryani there, breaking the dough seal. The fragrant steam will escape and you can serve just like that or pile on to a platter and garnish with fresh mint leaves, coriander, crispy onions and dried rose petals.
