Creamy Mussel Bisque

Ingredients

Equipment Needed

• •Large Dutch oven or heavy-bottomed pot with lid (6-quart minimum)
• •Fine-mesh strainer
• •Cheesecloth or coffee filters
• •Blender (countertop preferred for smoothest texture)
• •Stiff brush for scrubbing shells

Instructions

1. 1

   Inspect and clean mussels

   Spread your mussels on a sheet pan and examine each one. Discard any with cracked shells or shells that won't close when tapped sharply. A live mussel clamps shut when disturbed. A dead mussel stays open. Pull away any beards (the fibrous threads protruding from the shell) with a firm tug toward the hinge end. Rinse under cold running water, scrubbing away any grit with a stiff brush. Work quickly. Mussels are happiest cold.

   Fresh mussels smell like clean ocean water. Any ammonia smell means they've turned. Trust your nose.
2. 2

   Steam mussels open

   Set a large Dutch oven or heavy pot over high heat. Add 2 tablespoons of butter and let it foam. Add half the sliced shallots and cook for 30 seconds, just until fragrant. Pour in the wine, let it come to a rolling boil, then add all the mussels. Cover immediately. Shake the pot once or twice during cooking. After 4 to 5 minutes, the shells will have opened and released their liquor into the wine. Remove from heat. The mussels are done when they've opened. Overcooking makes them rubbery.

3. 3

   Separate mussels and strain liquor

   Using a slotted spoon, transfer mussels to a bowl. Discard any that refused to open. Line a fine-mesh strainer with cheesecloth (or a coffee filter in a pinch) and set it over a large measuring cup or bowl. Pour the cooking liquid through slowly. You want every drop of that liquor, but none of the grit. You should have about 2 cups of intensely briny, wine-perfumed liquid. This is the soul of your bisque.

   Reserve 18 to 24 of the prettiest mussels in their shells for garnish. Remove the meat from the rest and set aside.
4. 4

   Build the aromatic base

   Wipe out the Dutch oven and return it to medium heat. Add the remaining 2 tablespoons butter. When it foams, add the remaining shallots, the celery, and the fennel. Cook, stirring occasionally, until softened and translucent, about 8 minutes. The vegetables should not brown. Add the garlic and cook 1 minute more until fragrant. Your kitchen will smell like a French bistro by the sea.

5. 5

   Create the roux

   Sprinkle the flour over the vegetables and stir constantly for 2 minutes. This cooks out the raw flour taste and creates the base for a smooth bisque. The mixture will look pasty and coat the vegetables evenly. Don't let it color. A blonde roux is what you're after.

6. 6

   Add liquids and simmer

   Pour in the reserved mussel liquor, whisking constantly to prevent lumps. Add the fish stock, bay leaf, and thyme sprigs. Bring to a gentle simmer. Reduce heat to medium-low and cook uncovered for 25 to 30 minutes, stirring occasionally. The bisque base will reduce slightly and the flavors will concentrate. It should coat a spoon but still flow freely.

7. 7

   Puree until silken

   Remove and discard the bay leaf and thyme stems. Add the shelled mussel meat to the pot (reserve those garnish mussels). Working in batches, transfer the soup to a blender and puree until completely smooth. Hold a towel firmly over the lid. Hot liquids expand and will blow the top off if you're not careful. For the silkiest result, strain the pureed bisque through a fine-mesh sieve back into the pot, pressing on the solids. This step is optional but worth the effort for company.

   An immersion blender works but won't achieve the same velvety texture. For special occasions, use the countertop blender and strain.
8. 8

   Finish with cream

   Return the bisque to medium-low heat. Stir in the heavy cream and warm through without boiling. Add the cognac if using (it adds a subtle warmth that complements the brine beautifully). Squeeze in the lemon juice. Add the cayenne. Season with salt and white pepper, tasting as you go. The bisque should taste deeply of the sea, rounded by cream, brightened by acid. It will be coral-pink and flow like satin from a ladle.

9. 9

   Serve with ceremony

   Ladle the hot bisque into warmed bowls. Nestle 3 or 4 of the reserved shell-on mussels into each portion. Scatter minced chives over the surface and lay a few delicate fennel fronds across the top. Serve immediately with thick slices of crusty sourdough for dragging through every last drop. This is food meant to be eaten slowly, with good wine and better conversation.

Chef Tips

• •Seek out sustainably rope-farmed mussels from Penn Cove, Taylor Shellfish, or similar Pacific Northwest operations. Farmed mussels are among the most environmentally responsible proteins you can buy. They filter water as they grow, requiring no feed, no antibiotics, no freshwater input.
• •The mussel liquor is liquid gold. If you have time, refrigerate it overnight. Any remaining grit will sink to the bottom, and you can pour off the clear liquid from above.
• •A dry Muscadet from the Loire Valley is the classic pairing here. Its mineral salinity echoes the mussels beautifully. Washington State Sauvignon Blanc or an unoaked Chardonnay from Oregon also serve well.
• •If fennel isn't available, substitute an equal amount of celery plus half a teaspoon of fennel seeds, lightly crushed.
• •The bisque reheats beautifully but will thicken as it sits. Thin with a splash of stock or cream when warming. Never boil once cream has been added.

Advance Preparation

• •The bisque base (through pureeing, before cream) can be made up to 2 days ahead and refrigerated. Reheat gently and add cream just before serving.
• •Mussels should be purchased the day you plan to cook them, or at most one day before. Store in the refrigerator in an open container, draped with a damp towel. Never store in sealed plastic or submerged in water.
• •The garnish mussels can be steamed and shelled up to 4 hours ahead. Refrigerate in their shells, covered, and warm briefly in the hot bisque before serving.
