["Melt butter in large pan. Add onion and garlic, stirring over medium heat until onion is soft (about 3 minutes). Mix in mushrooms and stir about 5 minutes. Add flour and stir for another minute. Pour in milk and beef stock, stirring well until combined and bring to a boil; reduce heat to low. Simmer, uncovered, for 15 minutes or until mixture has reduced, is thickened and mushrooms are tender. Add parsley. Serve with a dollop of sour cream."]
