Peel the potatoes and cut them in halves. You can boil them until it's half cooked and fry them before adding them to the Pilaf or you can add them raw. I did parboil one and I fried them
Fry 2 of the onions until crisp in enough oil to cover the onions. First fry on high heat for about a minute, reduce the heat and fry until crisp and golden brown. Set aside
Cut the vegetable, rinse well and set aside
Heat oil in a large flat pot. Add the whole spices, cinnamon, black cardamom, bay leaf, cloves and star aniseed and fry until fragrant
Add the remaining onion and thyme and sauté until the onion is golden brown
Add the ginger/garlic paste and sauté for a minute
Add the vegetable, excluding the potatoes and sauté for 2-3 minutes
Add the ground spices, masala, chilli powder, turmeric, cumin, coriander, fennel and garam masala. Mix well and sauté for 5 minutes. You an add a few drops of water to prevent burning
Add the blended tomatoes, tomato paste and mint. Season with salt and simmer for about 30 minutes or until vegetables are tender. You can add a half cup of water if liquid dries up before the veggies are cooked
Preheat oven to 180 degrees Celsius
Add the rice and potatoes once the veggies are cooked and mix well. Pour 2 cups of water over the rice and place the butter on top. Sprinkle the onion on top
Pop the Pilaf into the oven for an hour or until the rice and potatoes are cooked
After an hour if the rice and potatoes are still not completely cooked you can add another cup or 2 of water and cook for a further 30 minutes. You should have an idea as to how much cooking time is needed after an hour so add just enough liquid to allow it to finish cooking
