Heat the oven to 200C/180C fan/gas 6. Drizzle oil over the beetroot and sprinkle with salt and pepper. Toss to coat, then tip into a roasting dish and cook for 25-30 mins or until tender.
While the beetroot is cooking, heat the remaining oil in a deep frying pan (or a wok) with a lid.
Fry the onion over a medium heat until golden.
Add the ginger and half the garlic, and cook for 1 min.
Stir through the bay, cardamom seeds, turmeric and garam masala, then cook for 2 mins.
Stir in the rice and beetroot.
Pour in the stock and place a fitting lid on the pot
Boil for 20-25 minutes, keeping an eye on to make sure it doesn't dry out or burn to the bottom of the pan.
Put the remaining garlic in a food processor and whizz, then add the yoghurt till it's well blended. Set aside.
Remove rice from heat and stir through.
Season to taste and serve.
