- 8ounces unsalted butter
- 1medium red onion, peeled and thinly sliced
- 2cloves garlic, peeled and thinly sliced
- 8shiitake mushroom stems
- 1medium ripe tomato, coarsely chopped
- 1bay leaf
- 1teaspoon black peppercorns
- ⅓cup balsamic vinegar
- ⅓cup water
- Salt and freshly ground black pepper to taste
Preparation
- Step 1
Cut 6 tablespoons of the butter into ½-inch cubes. Refrigerate. Melt the remaining butter in a large saucepan over medium heat. Add onion, garlic, mushroom stems, tomato and bay leaf. Cook, stirring occasionally, until the vegetables are soft but not brown, about 6 minutes.
- Step 2
Add vinegar and water. Reduce over medium high heat until just a syrupy liquid remains, about 8 minutes. Lower the heat slightly. Whisk in the cold butter, 2 to 3 pieces at a time, allowing each addition to be absorbed before adding the next. Strain through a fine sieve. Season with salt and pepper. Keep warm over a double boiler.

Excellent with the recipe "sauteed salmon with sweet corn" and probably a good sauce for many such dishes. Mild and flavorful. The peppercorns go in with the mushroom mixture as they are omitted from the directions. I used the stems from mixed mushrooms, not just shiitake.
