For the Mixed Mushroom Conserva


1. Just before cooking, rinse the mushrooms as necessary to remove any dirt. Remove any stems that are tough, such as the stems ofshiitake mushrooms and discard or set aside for another use, such as a vegetable stock. Trim the end of other stems as well as anybruised areas.

2. Cut the mushrooms into pieces. The size and shape will vary with the variety of the mushroom.

3. Small mushrooms can be left whole, larger mushrooms can be cut into chunks or into slices.

4. Some mushrooms with meaty stems such as porcini or trumpet mushrooms, can be cut lengthwise in half.

5. Use the tip of a paring knife to score the inside of the stem in a crosshatch pattern. This will enable the marinade to penetrate the stem. The pieces of mushroom will shrink as they cook, but the finished pieces should not be larger than one bite. You should have about 1.5 pounds (10 cups) of trimmed mushrooms.

6. Place the olive oil, bay leaves, thyme sprigs, rosemary and Piment d'Espelette in a large, wide saucepan over medium to mediumhigh heat.

7. Place a thermometer in the pot and heat until the oil reaches 170 degrees F, stirring the mushrooms in the oil from time to time. It may benecessary to tilt the pot and pool the oil to get a correct reading on the thermometer. Adjust the heat as necessary, to maintain thistemperature for 5 minutes.

8. Add the mushrooms to the pot, and gently turn the mushrooms in the oil.

9. When the oil reaches 170 degrees F again, maintain the temperature for 5 minutes, gently turning the mushrooms from time to time. Themushrooms will not initially be submerged in the oil, but will wilt as they steep.

10. After 5 minutes, turn off the heat and stir in the vinegar and salt and pepper to taste.

11. Let the mushrooms steep in the oil for 45 minutes.

12. Place the mushrooms, oil and herbs in a covered storage container.

14. Kept covered in oil the mushrooms will keep for up to 1 month in the refrigerator.

Reheat mushroom conserva in a sauté pan.

Spoon mixed mushroom conserva and sauce on the bottom of a shallow bowl.
