In a saucepan, combine water, wine, olive oil, lemon juice and bouquet garni. Simmer for 10 minutes. Slice mushrooms and leave small ones whole. Add mushrooms to court bouillon and simmer 8 to 10 minutes. Strain out mushrooms and reduce cooking liquid by two-thirds or until thickened. Allow mushrooms to marinate overnight in sauce.
