Cover cleaned and roughly chopped 1-2 pounds chanterelle mushrooms with water in a large saucepan. Bring to a boil and then immediately remove from heat and drain completely.
Chop raw ½ pound bacon into 1 inch pieces. Fry until crisp. Drain off most of the fat, leaving some to sauté the mushrooms and onion. A tablespoon or two will do.
Add the 1 onion to the bacon and remaining grease. Cook over medium heat until they start to become translucent. Add the well drained mushrooms and saute for a couple of minutes, stirring occasionally.
Sprinkle with 1 Tablespoon all-purpose flour and cook for another minute or two, stirring frequently, to cook the flour taste out.
Stir in the ½ cup milk and cook until it starts to thicken.
Remove from heat and stir in the ¼ cup sour cream. Adjust your salt and pepper to your liking.
