For the roasted butternut- this can be done in advance, or used straight from the oven.
Preheat the oven to 180c.
Cut the butternut in half. Scrap out the seeds. Brush with oil and bung the halves onto a baking tray.
Whack in the oven for around 1 hour or until the butternut is completely soft.
For the soup. In a saucepan fry onions in the coconut oil till soft and transulcent, about 5 mins. Add in the spices, garlic and ginger, cook for 2 mins stirring regularly.
Whack in the remaining ingredients, bring up to the boil and simmer for a couple of mins.
Pour into a blender and blitz till smooth- you may have to do this in batches to achieve a velvet smooth texture.
If eating straight away, add back into the pan and heat till warm.
