To prepare the polenta: Boil water with salt and milk. Whisk in the coarsely ground maize flour, keep stirring till all the lumps are broken. Cook on a hot plate or low heat for 40 minutes, stirring occasionally. Grease a tray and pour onto it and cool. Cut the polenta into desired shape and size. Shallow fry in butter till the outside is crisp and golden in colour. Serve hot with the mushroom sauce.
