Wild Mushroom Soup

1. If using fresh morels, cut in half and briefly swish in a large bowl of tepid water. Drain and repeat to remove all the dirt. Gently but thoroughly pat dry, then coarsely chop. (If using dried morels, soak in 2 cups warm water for 30 minutes. Strain in a cheesecloth-lined sieve and reserve the soaking liquid. Add enough broth to the soaking liquid to equal 5 cups. Coarsely chop the morels and creminis.)

2. Heat oil in a large pot over medium heat. Add carrot, celery and onion; cover and cook, stirring occasionally, until the vegetables are tender, 8 to 10 minutes. Add garlic and cook, stirring frequently, for 30 seconds. Add Marsala and cook for 1 minute more.

3. Add the broth, the fresh mushrooms (and dried, if using), potato, thyme, salt and crushed red pepper. Bring to a boil. Reduce heat and simmer, uncovered, until the potato is tender, 15 to 20 minutes.

4. Puree the soup with an immersion blender or in a regular blender or food processor. Stir in pepper. Serve the soup garnished with parsley and a drizzle of oil, if desired.

Tips

Tip: Marsala, a fortified wine from Sicily, is a flavorful addition to many sauces. Don't use the “cooking Marsala” sold in many supermarkets--it can be surprisingly high in sodium. Instead, purchase Marsala that's sold with other fortified wines in your wine or liquor store. An opened bottle can be stored in a cool, dry place for months.

To make ahead: Cover and refrigerate for up to 3 days.
