Make the duxelle from the stems of the 'bellos ... and maybe even add a few other mushrooms for some added flavor.
Chop the 'shrooms real fine. For argument's sake, lets say a total of a pound of 'shrooms and/or 'shroom parts. Chop real fine some gahlic or shallotts. Couple of ounces worth'll do it. Unless you're me. Or your name's Valdimir ...... anyway ......
Mix 3 parts white wine and 2 parts heavy cream to get a total of about 6 ounces.
Salt and pepper to taste.
Mix all that together and set it on the stove. Let it go at a low boil until it is nearly a dry mixture. Careful. It can catch and scorch.
Now the secret ingredient(s) ...... Beurre Manie.
Mix equal parts butter and flour. Say a total of about 1/4 cup (what's that? 4 table spoons or so ... maybe two of each). Mix this together until it is all combined than rub it in your hands to form little balls of it.
Take the 'shroom stuff off the fire and add the beurre manie. Don't put it back on the heat. The beurre manie will thicken the whole lot. Mix it all up and top the 'bellos. Top that with your stuffing.
Now ...... whatever flavor you're using as the key to your stuffing, use that in the duxelle. Let's say you're using sage sausage. Add some sage to the duxelle. The duxelle can also stand on tis own, but adding the flavor to the duxelle kinda pulls it all together. Even better if you use 'shrooms in your stuffing. This will form a nice layer of surprise for your guests. and the best part ...... s'easy to do.
Make 'em ahead of time and bake 'em off just before serving.
Gobble gobble :)
Oooops!
I meant this one!
