- 5 pounds fresh fava beans, shelled
- 1 stick (4 ounces) unsalted butter
- 1/2 cup finely chopped onion, plus 2 medium onions, thinly sliced
- Salt and freshly ground white pepper
- 4 garlic cloves, thinly sliced
- 4 cups Chicken Stock
- 2 thyme sprigs
- 1/4 cup balsamic vinegar
- 12 baby leeks or large scallions, trimmed, leeks rinsed well
- 3 tablespoons extra-virgin olive oil
- 24 fresh morels (about 4 ounces), rinsed well and patted dry
- 2 teaspoons coarsely chopped chives
- 1 teaspoon minced shallot
- Six 6-ounce striped bass fillets, about 1 1/4 inches thick
- 1 teaspoon white truffle oil
- In a large saucepan of boiling water, cook the fava beans for 2 minutes. Drain and refresh under cold running water. Peel off and discard the tough bean skins.
- In a large deep skillet, melt 2 tablespoons of the butter. Add the chopped onion and cook over moderate heat, stirring, until softened, about 7 minutes. Add all but 1/2 cup of the fava beans and cook for 2 minutes; transfer to a food processor. Blend until smooth, adding a little water if the fava bean puree is too stiff. Add 1 tablespoon of the butter and process until incorporated. Season with salt and white pepper.
- Melt 2 tablespoons of the butter in the skillet. Add the sliced onions and cook over moderately high heat, stirring, until soft and caramelized, about 20 minutes. Add the garlic and cook until softened, 2 to 3 minutes. Add the Chicken Stock and thyme and boil until reduced by half, about 17 minutes. Add the balsamic vinegar and simmer for 5 minutes. Strain the sauce into a medium saucepan, pressing on the solids. Boil the sauce until reduced to 1 cup.
- Heat a grill pan. Pat the leeks dry with towels and toss with 1 tablespoon of the olive oil. Season with salt and white pepper and grill over moderate heat until tender and charred all over, about 8 minutes.
- Heat 1 tablespoon of the butter in a medium skillet until lightly browned. Add the morels and cook over moderately high heat until softened, about 5 minutes. Add the reserved 1/2 cup of fava beans, 1 teaspoon of the chives and the shallot and cook for 1 minute. Season with salt and white pepper.
- Preheat the oven to 400°. In each of 2 ovenproof skillets, preferably nonstick, heat 1 tablespoon of the olive oil until shimmering. Season the fish with salt and white pepper and add the fillets to the pans, skin side down. Cook over high heat just until opaque around the edges, about 3 minutes. Transfer the skillets to the oven and roast the fish for about 11 minutes, or until the flesh flakes at the thickest part.
- Meanwhile, bring the sauce to a simmer over low heat. Whisk in the remaining 2 tablespoons of butter and 1 teaspoon of chives. Whisk in the truffle oil and season with salt and pepper; keep warm but do not boil. Rewarm the fava bean puree and sautéed morels on top of the stove and the grilled leeks in the oven.
- Spoon the morels onto 6 warmed plates. Set the fish, skin side up, on the morels, and top with the leeks. Spoon the fava bean puree alongside, pour the sauce around the fish and serve.
The fava bean puree, sauce and leeks can be prepared through Step 4 and refrigerated overnight.

Pinot Noir has the fruitiness to stand up to the rich onion sauce and the mushrooms but is light enough to balance the striped bass.
