Cream of Mushroom Soup

If you’re making a batch of duxelles, why not make a double batch?! This mushroom soup is as easy as a recipe gets if you have the duxelles.

2 c. duxelles
4 c. chicken broth or stock
4 T. cornstarch
2 c. heavy cream

Combine the duxelles and broth in a suitable pot, and bring to a boil. Reduce to a simmer, and cook for 30 minutes.

Combine the cornstarch with about 1/2 c. of the cream,

and whisk together until smooth. With the soup still simmering, pour the cream and cornstarch mixture in, and whisk until combined. The soup should immediately thicken. Continue to simmer for 10 minutes, then remove from the heat.

Add the remaining cream, and shisk to combine. Season to taste with salt and pepper. Serve right away, or refrigerate until needed.

David Gingrass is a food and beverage operations professional with a career spanning more than three decades. His fascination with and love for food, wine and entertaining allows him to view his work as both a vocation and an avocation. Gingrass graduated from the Culinary Institute of America in Hyde Park, New York then cooked in the Bay Area for two years before landing a job at Wolfgang Puck’s original Spago Restaurant in West Hollywood. There he learned to make the signature breads and sausages that he became known for at Postrio and Hawthorne Lane. He was soon promoted to kitchen manager and managed the operational and expense control aspects of Puck’s iconic restaurant for the next four years. Gingrass returned to San Francisco in 1989 when Puck tapped him and his then-wife Anne to open Postrio, Puck’s third restaurant and his first outside of Los Angeles. Postrio opened to rave reviews and soon became the #1 popular Bay Area restaurant in the prestigious Zagat survey. Five and a half years later, the opportunity to open a restaurant of his own presented itself. Hawthorne Lane opened in 1995 and was a San Francisco dining institution for over twelve years, catering to the likes of Julia Child, Jacques Pepin, Mayor Willie Brown, James Carville, President Clinton and First Lady Hilary Clinton. He closed Hawthorne Lane at the end of its fifteen-year lease in 2009 to build a consulting practice for the hospitality industry, sharing his wealth of culinary and operational experiences with new and existing restaurants, assisting them to become successful and profitable.
