I start these by peeling off the caps and slicing them. I add a little butter and olive oil to a pan and saute some chopped onion. When it's translucent, I add the mushrooms along with some fresh thyme leaves.
When the liquid evaporates and the mushrooms are cooked, I finish them off with just about a tablespoon of cream to give a silky texture. These mushrooms are not as firm as those from the store--they have thinner caps--but they have such a delicious woodsy mushroom flavor! The first few times I had cultivated mushrooms I thought they were rubbery compared to these.
My absolute favorite way to eat these is just over boiled, fork-mashed, salted potatoes. And, today, I treated myself to some marinated herring in sour cream on the side. (My husband said I just lost him there--he wants no part of the herring.) My drink of choice for this meal is cold fresh buttermilk.
