If you want to really enhance that..get a samll pakage..2 oz of dried porcini mushrooms..you rehydrate them in 1 1/2 cups of hot water for about 30 minutes..strain them...and reserve the liquid..pour most of liquid off CAREFULLY into a small sauce pan...because any sediment/grit will settle to the bottom, and you don't want that..bring the liquid to a boil, lower to simmer, until liquid is down to 1/2 cup or so..( take a taste..the intense flavor will astound you..)add mushrooms and liquid to your mixture when you add the mushroo soup..
enjoy
I have to go to the store today, so I'll try to pick some up. Thanks!
