Preheat oven to 475º F
Make a Béchamel Sauce by combining over a double boiler or Bain Marie,
3 tbs. Butter
1/2 cup flour
Add a scant cup cold milk and continue to whisk over the steam heat until thickened. Season with salt, pepper and nutmeg. Add blended mushroom mixture (sautéed onion, 1 cup chopped mushrooms, 1/4 cup toasted pine nuts and deglazed with wine). Then add 4 – 5 egg yolks from large eggs. Fold in 4-5 egg whites, whisked to stiff peaks.
Use a buttered and floured soufflé mold or 6 smaller ramekins. Pour in the mixture and bake in the oven at 400ºF for 30 minutes (less time if using ramekins) without opening the door during cooking, until well-risen and a deep golden-brown on top.
