A rich sauce for chicken or pasta. If chantrelles are not in season, use dried (soak them first) or other fresh mushrooms. As suggested by a reviewer, replace some of the marsala with broth if you feel the wine flavor would be too strong.
Melt butter in heavy skillet over medium heat. Add the shallots and garlic; sauté 5 minutes. Stir in the mushrooms and sauté until they start to give off their liquid, about 5 minutes. Spoon out mushrooms and keep warm.
Whisk flour, paprika, salt and pepper into the butter and cook over medium-low heat 1 minute. Stir in the Marsala and whisk until blended. Add mushrooms back to mixture and simmer 5 minutes.
