My husband makes the most delicious mushroom sauce. This is really easy.
Start by adding some butter in a pot. Add in some chopped mushrooms. Fry in the butter till soft. Add in about a cup of milk or more. Place heat on high and turn down.
Mix a few teaspoons of cornflour with some water, and add to the milk and mushroom mixture. Stir until the sauce thickens. Set aside and serve with your favourite meat or chips.
Enjoy!
