3 tbls finely chopped shallots
1/2 lb finely chopped mushroom stems
2 tbls unsalted butter
2 tbls flour
3/4 cup heavy cream
1/2 tsp salt
1/8 tsp cayenne
1 tbls chopped chives
1/2 tsp lemon juice
2 tbls parmesan cheese
1/2 lb fresh mushroom caps, cleaned

[i have only used this recipe with agaricus/white mushrooms. i'm quite sure it would be excellent with other varieties. as for the parm, you can use anything from the processed stuff to parmigiano-reggiano...still tastes good]

saute shallots in butter under moderate heat, about 4 min
stir in chopped mushroom stems, cook until moisture is evaporated [about 10-15 min]
remove from heat, sprinkle flour over mixture and stir.
add cream and return to heat
bring to a boil, mixture will thicken heavily
stir in all seasonings, pour into a bowl and let cool
refrigerate until ready to use [i recommend chilling for at least an hour or two]

take mixture and spoon into the caps, mounding slightly.
sprinkle with parmesan cheese
bake at 350 for 10 min

let cool for 5-10 before serving

enjoy!
