Oyster Bisque with Herbsaint

Ingredients

Equipment Needed

• •Heavy-bottomed Dutch oven or large saucepan
• •Fine-mesh strainer
• •Whisk
• •Ladle

Instructions

1. 1

   Prepare the oysters

   Strain the oysters over a bowl, reserving every drop of that precious liquor. That liquid is pure ocean flavor, concentrated essence of the Gulf. Pick through the oysters gently, checking for shell fragments. Give them a quick rinse only if you find grit. Set the oysters aside and measure the liquor. You should have about a cup. If you're short, top it up with clam juice.

   Cold oysters straight from the refrigerator hold their shape better when poached. Let the bisque base cool slightly before adding them.
2. 2

   Build the blonde roux

   Melt the butter in a heavy-bottomed Dutch oven over medium heat. When it foams and the foam subsides, whisk in the flour all at once. Keep that whisk moving constantly. For a bisque, you want a blonde roux, the color of peanut butter, which takes about five minutes. You'll smell a nutty, toasted aroma when it's ready. This is where the silky body comes from.

   A blonde roux thickens more than a dark one. It's the right choice here because we want body without competing with the oysters' delicate flavor.
3. 3

   Sweat the holy trinity

   Add the onion, celery, and bell pepper to the roux. The mixture will seize up and get pasty. That's exactly right. Stir constantly and cook until the vegetables soften and turn translucent, about eight minutes. They should smell sweet, not raw. Add the garlic in the last minute. Garlic burns fast, so keep it moving.

4. 4

   Deglaze with wine

   Pour in the white wine and watch it bubble furiously as it hits the hot pot. Scrape up any fond stuck to the bottom. This is flavor you've built. Let the wine reduce by half, about three minutes. The sharp alcohol smell should mellow into something softer and more complex.

5. 5

   Add liquids and season

   Stir in the reserved oyster liquor and seafood stock. Add the salt, white pepper, cayenne, bay leaves, and thyme. Bring to a gentle simmer and let it cook uncovered for fifteen minutes. The base will thicken slightly and the flavors will marry. Taste it now. Season it now. The cream will mute everything later, so this base needs to be bold.

   White pepper instead of black keeps the bisque looking clean and elegant. Save the black pepper for heartier dishes.
6. 6

   Finish with cream

   Reduce heat to low. Pour in the heavy cream in a slow, steady stream while stirring constantly. You're tempering here, bringing the cream up to temperature without shocking it. Let the bisque simmer gently (never boil) for another ten minutes until it coats the back of a spoon. Remove the bay leaves.

7. 7

   Poach the oysters

   Slip the oysters into the simmering bisque. They need only two to three minutes, just until the edges curl and they plump up. Overcooked oysters turn rubbery, and that's a tragedy nobody should suffer. The moment you see those edges ruffling, pull the pot off the heat.

   At Lagniappe, we poach the oysters in a separate pan of bisque, then ladle them into each bowl. This way the pot stays perfect for seconds.
8. 8

   Add the Herbsaint

   Stir in the Herbsaint off the heat. That anise perfume will bloom immediately, filling your kitchen with the smell of New Orleans. Taste one more time. Adjust salt if needed. The bisque should be rich, briny, slightly sweet from the cream, with that haunting licorice note dancing at the edges.

9. 9

   Serve immediately

   Ladle the bisque into warmed bowls, making sure each serving gets four plump oysters. Scatter fresh chives and parsley over the top. A few drops of good butter floated on the surface wouldn't hurt a thing. Serve with crusty French bread for soaking up every last drop. This is the kind of soup that makes people close their eyes.

Chef Tips

• •Buy your oysters from a reputable fishmonger and use them within two days. Fresh Gulf oysters should smell like clean ocean, never fishy or sulfurous. If they smell off, they are off.
• •The bisque base can be made a day ahead and refrigerated. Reheat gently and poach the oysters just before serving. This actually deepens the flavor.
• •For a dinner party, warm your bowls in a low oven while the oysters poach. Cold bowls cool hot soup too fast, and this bisque deserves to be savored slowly.
• •A crisp Muscadet or dry Champagne stands up beautifully to the richness here. The acidity cuts through the cream while respecting the oysters.

Advance Preparation

• •The bisque base (through step 6, before adding oysters) can be made up to one day ahead and refrigerated. Reheat gently over medium-low before proceeding.
• •Oysters must be poached fresh, just before serving. They cannot be reheated without turning tough.
• •Shuck your own oysters up to four hours ahead if you prefer, storing them in their liquor in the refrigerator.
