Mushrooms on butter toast
1/2 pound cremini mushrooms, or a mix of wild mushrooms such as shiitakes, oysters or chanterellas
2 tablespoons unsalted butter, more for toast
1 large or 2 small shallots, chopped
2 tablespoons dry white wine or white vermouth
1/4 cup heavy cream
Kosher salt and freshly ground black pepper
Slices brioche or good white bread, crusts cut off if desired
1 tablespoon fresh chopped chives
Coarse sea salt such as fleur de sel or Maldon, for garnish
Clean excess dirt from mushrooms. Slice mushrooms in half lengthwise and brush away any grit; chop into 1/4-inch pieces.
Melt butter in a large skillet over medium-high heat. Add shallots and sauté until very limp, about three minutes. Add mushrooms and cook, stirring, for about five minutes. Add wine, reduce heat to medium, cover, and cook for about five minutes more. (There are a lot of “abouts” on the cooking times because I found that mine took less time at each step; however, I also may have chopped my mushrooms and shallots smaller than the recommended size.)
Uncover pot and continue cooking, stirring occasionally, until most of the liquid has evaporated, about two minutes. Stir in cream; simmer until slightly thickened, two minutes longer. Season with salt and pepper to taste.
Toast bread and spread with butter. Cut each slice in half diagonally and sprinkle lightly with chives. Top each toast triangle with some mushroom mixture. Sprinkle with additional chives, garnish with sea salt, and serve.
