Brown Mushroom and Spinach Soup Katrine SchleigerJuly 28, 2017AutumnRecipesWinter Such a deliciously satisfying and hearty mushroom soup. It’s Adam Liaw’s recipe and one of my favourites. Vegemite is a winner, who would have thought! It gives an extra savoury umami edge. I hope you try this and enjoy it as much as I do.
