Put the oil from the roasted butternut squash and the remaining oil into a deep pan with the spring onions and the bay leaves. Cook for 2-3 minutes. Stir in the garlic and rice then cook for a further 1 minute. Pour in the wine and simmer on a medium heat until it has absorbed into the rice. Pour in some of the stock and simmer until this has absorbed into the rice. Carry on this process until all the stock is used and the rice as cooked. If the rice is not cooked after all the stock is used, water may be used in place of stock until the rice is cooked.
