This makes an impressive dish for a party that can be made and then left to cook in the oven unattended for a couple of hours. A 4 kg. pumpkin will give 8 good portions, or more if served with other dishes.
You’ll need a large, fleshy pumpkin the one I used was about 4kgs a pumpkin that’s heavy for it’s size will have good dense flesh. pre-heating your oven to 200 degrees C / 400F. Then make the stuffing. Chop and fry an onion in some vegetable oil add 2-3 crushed cloves of garlic a tsp. of salt, a tsp. cumin seeds, a tsp. mustard seeds and a tsp. turmeric powder. Gently fry and then add a chopped red pepper and about 200g chopped mushrooms. Fry for a few minutes then add 2 handfuls of cashew nuts, a handful of sultanas, 1 1/2 cups of brown rice and 1/2 cup red lentils. Next I added a small bottle (275 ml.) cider and then cover the mixture by a couple of cm. with boiling water (you can use veggie stock instead of cider and water if you prefer) and put a lid on the pan an simmered for about 15 minutes.
Meanwhile wash your pumpkin and cut a lid out of the top of the pumpkin and scoop out all the seeds and the softest layer of flesh inside. In a mortar crush a clove of garlic with a pinch of salt, a few peppercorns, about a 1/4 tsp. nutmeg and 1/2 tsp. coriander seeds. Smear this on the inside flesh of the pumpkin. Check your rice to see how it’s doing you want it to be about 3/4 cooked so still a little hard and to still have a reasonable amount of liquid in it. Once the rice is almost cooked taste it and season with extra salt, if necessary, then scoop it into the pumpkin and put the lid on. Loosely wrap the pumpkin in foil to stop the outside burning and put it in the oven for about 2 – 2 1/2 hours. The cooking time will depend of the size and density of your pumpkin.
To serve I made a simple sauce that Ottolenghi uses with roast pumpkin. Mix 8 tbsp. of plain yoghurt and 2 – 3 tbsp. of Siracha sauce together. It looks good if it’s not completely mixed together. I also finely chopped a couple of spring onions and added them to the sauce. Once the pumpkin is cooked place on a serving dish. To serve take off the lid and cut slices of the pumpkin and filling and serve with the sauce and some fresh coriander leaves.
