Roast your BNS. Spray and then sprinkle with salt and pepper or garlic powder if you have any.
Roast it for 30-40 mins at 180 degrees.
In the meantime finely slice an onion and fry until brown on a medium heat. You will need to add water a little at a time to avoid sticking. Add some garlic and ginger.
Make some stock. Any will do. 500ml of it and add to the browned onions. Bring to the boil and then reduce for about 20 mins.
Take the BNS out of the oven and add to the onion and stock mix. Add another 300ml of stock. Bring to the boil and reduce. Blitz it and then reduce to your desired consistency or add more water if it's too thick.
Check for seasoning at the end and add salt, pepper, chilli at the end x
Beautiful soup. Love BNS.
