I got the inspiration from Hope Miller who is Orson Miller's wife. Orson Miller was a renowned mycologist and wrote a very good book about North American Mushrooms (http://www.amazon.com/North-American-Mushrooms-Inedible-Falconguide/dp/0762731095/ref=sr_1_1?ie=UTF8&qid=1296658756&sr=8-1). I met Hope and Orson the summer before he died, at a Utah Mushroom Society foray along the Mirror Lake Highway. Hope made a version of this recipe but I didn't quite agree with the way that she made it so I came up with this method.
I usually serve this hot with wavy potato chips. It is kind of thick so regular potato chips won't stand up to being dipped in it. I have used different kinds of mushrooms for this. White button mushrooms work well but I really like more flavorful mushrooms in this too. The brown mushrooms that are more common in stores now work really well. I've also made it with wild morels, wild oyster mushrooms, fresh shitaki mushrooms, and chanterells. Also, I usually use Better than Bouillon chicken bouillon. I love Better than Bouillon products, it is so easy to use and it makes things taste so good. I add it to all kinds of things, including mashed potatoes, gravy, clam chowder and Finnan Haddie (clam flavored).
This dip can also be used in other ways. I've been known to make cream of mushroom soup by adding milk or cream and chicken broth. You can also make an appetizer by placing a teaspoon of the dip on a long strip of phyllo dough then folding the phyllo dough over it like you would fold a flag to make a triangle of dough stuffed with mushroom dip. I would brush that with melted butter then brown them in an oven. My favorite way to use mushroom dip is to stir it into scrambled eggs then spoon my grandma's chili sauce over the top.
