This soup keeps well for the next day. Store in the fridge. Also freezes very well.
Preheat a biggish heavy based saucepan over high heat. Add butter, wait until it foams and then add the onion pre-seasoned with Green Onion Seasoning. Stir-fry until the onion is nicely browned and soft. Add the mushrooms and cook them with the onions until they start releasing water. Add the flour and cook for another 2 minutes while stirring.
Add the water, Liquid Beef Stock and Garlic Pepper Seasoning. Turn the heat right down, put a lid on the saucepan and simmer very slowly for 15-20 minutes. Grate a little nutmeg over the soup just before serving.
We make an excellent Mushroom Liquid Stock for Woolworths. Replace two sachets of the Beef Stock with the Mushroom Stock.
