  • 1 cup dry white wine
  • ½ cup white wine vinegar
  • 1 Tbsp finely chopped shallot
  • 1 cup unsalted butter, cold
  • Kosher salt, to taste
Mushroom Preparation
  1. Preheat broiler.
  2. Remove brown gills from the undersides of mushrooms using a spoon; discard gills
  3. Place mushrooms, gill sides down, on a foil-lined baking sheet coated with cooking spray.
  4. Broil the mushrooms for 5 minutes.
  5. While mushrooms broil, combine the tomatoes, panko breadcrumbs, cheese, and chives.
  6. Remove mushrooms from broiler.
  7. Turn mushrooms over, and sprinkle evenly with salt and pepper. Divide tomato mixture evenly among mushrooms.
  8. Return to broiler for approximately 5 minutes or until cheese melts.
  9. Swirl Beurre Blanc on to serving plate, placing mushrooms on top.
  10. Top warm mushrooms with remaining Beurre Blanc
Beurre Blanc Preparation
  1. Heat wine, vinegar and shallots in a saucepan until the liquid boils, then lower the heat a bit and continue simmering until the liquid has reduced down to about 2 tablespoons.
  2. While the liquid reduces you can cut the butter into medium (½-inch) cubes, but either leave this until the reduction is nearly finished or return the butter cubes to the refrigerator to keep them cold while the liquid finishes reducing.
  3. Once the wine-vinegar mixture has reduced to 2 tablespoons, reduce the heat to low and start adding the cubes of butter, one or two at a time, and whisk rapidly with a wire whisk.
  4. As the butter melts and incorporates, add more butter and keep whisking. Continue until you only have 2-3 cubes remaining. Remove from heat while whisking in the last few cubes, and whisk for a moment or two more. The finished sauce should be thick and smooth.
  5. Pour through strainer to remove shallots. (You could leave these but your sauce will be lumpy)
  6. Season to taste with Kosher salt.
