"Earth, color, red things," are the words Pierre Gagnaire uses to describe the Hermès perfume that inspired his dish, Parfums de Terre. This marvelous soup is one of the dish's seven components. Both the foie gras that enriches the broth and the lentil gnocchi are earthy; the lightly pickled onion wedges add brightness and tang, not to mention a hint of color.
- 3 tablespoons unsalted butter
- 2 thick slices of lean bacon, finely chopped
- 1 small carrot, thinly sliced
- 1/2 small white onion, finely chopped
- 1/2 cup brown lentils
- 2 cups water
- 1/3 cup plus 1 1/2 tablespoons all-purpose flour
- 1/3 cup plus 1 1/2 tablespoons freshly grated Parmigiano-Reggiano cheese
- 1 large egg, beaten
- 1 large egg yolk
- 1/2 teaspoon salt
- 1/4 teaspoon freshly ground pepper
Balsamic Onion Wedges
- 1/2 small red onion, cut into thin wedges
- 1 tablespoon white balsamic vinegar
Foie Gras Broth
- 1/3 cup ruby port
- 1 cup chicken stock or low-sodium broth
- One 3-ounce slice of pure foie gras pâté, cut into 1-inch cubes
- Salt and freshly ground pepper
- Aged balsamic vinegar, for drizzling
- In a medium saucepan, melt 1 tablespoon of the butter. Add the bacon, carrot and onion and cook over moderate heat, stirring, until the onion is softened, about 4 minutes. Add the lentils and water, cover and simmer over low heat until the lentils are tender, about 30 minutes. Uncover and boil over high heat until most of the water has evaporated, about 5 minutes.
- Set aside 1/4 cup of the lentils. Transfer the remaining lentils and any liquid to a food processor and puree. Pass the puree through a coarse strainer into a large bowl; you should have about 1 cup.
- Bring a large saucepan of salted water to a boil, then reduce the heat so the water simmers. Set a large bowl of ice water nearby. Add the flour, cheese, egg, egg yolk, salt and pepper to the lentil puree and stir until a dough forms. Transfer the dough to a resealable plastic bag. Using scissors, cut a 1/2-inch diagonal opening from a corner of the bag. Working over the simmering water, pipe out and cut 1/2-inch pieces of the dough, letting them drop into the water. Cook the gnocchi until tender, about 4 minutes. Using a slotted spoon, transfer the gnocchi to the ice water to cool. Drain, gently pat dry with paper towels and transfer to a bowl.
- In a large nonstick skillet, melt the remaining 2 tablespoons of butter. Add the gnocchi and cook over moderate heat, stirring a few times, until lightly browned, about 3 minutes.
- Put the onion wedges on a microwave-safe plate and drizzle with the white balsamic vinegar. Cover with plastic wrap and microwave on high power for 1 minute.
- In a medium saucepan, boil the port over high heat until reduced by half, about 4 minutes. Add the chicken stock and bring to a boil. Pour the mixture into a blender and add the foie gras cubes. Puree until smooth, then pass the foie gras broth through a fine strainer into the saucepan. Warm the broth over moderately low heat, whisking constantly; do not boil. Season with salt and pepper.
- Rewarm the gnocchi. Spoon the gnocchi and the reserved lentils into 6 small bowls. Ladle the foie gras broth over the gnocchi and garnish with the onion wedges. Drizzle each serving with aged balsamic vinegar and serve right away.
Red wines from Burgundy (made with the Pinot Noir grape) are revered for their complexity and focused fruit, and are terrific partners for this luscious, earthy soup.
