Heat medium skillet to med/high heat. Melt butter, add chanterelle duxelle and cook for about one minute.
Pour wine into skillet, increase heat to high and cook until reduced by half (about 5 minutes).
Add cream, reduce heat back to med/high and cook, stirring occationally until desired thickness. *When sauce is moved across skillet, it's thick enough to slowly fill back in, but not too thick.
Notes
If you can't find chanterelle mushrooms, you can substitute any mushroom you like. If using fresh chanterelles, you'll need to triple the amount and add 1/4 more wine.
