Pan-Fried Frog's Legs, Homemade Alsatian Ravioli Filled with Onion Compote & Chervil Sauce

Antoine Westermann, Café 15, Hotel Sofitel Lafayette Square , Washington, D.C. / November 2002

To Italians, they're ravioli. To Chinese, they're wontons (or various dim sum treats). To European Jews, they're kreplach. Same rounds or squares of delicate dough (more or less), different fillings—a vivid illustration of ethnic accessorization. To wit: at Babbo (NYC), Mario Batali makes offal appealing by conjuring the various organs into flavorful ravioli fillings. Odette Fada has built her career at San Domenico (NYC) on the popularity of the soft egg yolk she slips into ravioli. And here, in a signature dish transported from his Michelin three-star Buersehiesel in Stratsbourg to his consultancy post at Café 15 in the Sofitel Lafayette Square in Washington, D. C., Antoine Westermann's refined onion compote lends ravioli an Alsatian twist.

For 4 servings

Onion compote:
• 2 Tbsps. unsalted butter
• 1 cup white onion, chopped
• salt
• white pepper, freshly ground
• 1/2 cup Sherry vinegar
• 1 cup crème fraîche

  1. Heat butter in a skillet set over medium-low heat; add onion; cover with circle of parchment paper; sweat until tender, without coloring, (about 20 minutes).

  2. Season; add vinegar; reduce to a syrup (about 15 minutes).

• 1 cup all-purpose flour
• 2 lg. eggs
• salt

  1. Work flour, eggs, and salt in large bowl into a dough by hand; envelop in plastic wrap; refrigerate 1 hour.

  2. Halve dough; flatten each half into a disc; pass each half through pasta machine several times, according to manufacturer's instructions; dust with flour to keep from sticking; continue to next-to-thinnest setting.

  3. Lay one sheet on work surface; brush lightly with water; place 16 1 tsp. mounds onion compote at 1" intervals; cover with remaining sheet; press around mounds areas to seal; cut out ravioli with 2" cookie cutter; place ravioli on sheet tray lined with parchment paper; reserve in refrigerator.

• 2 cups chicken stock
• salt
• white pepper, freshly ground

  1. Place frog backs on cutting board; separate legs using sharp knife; remove thigh bones from legs, scraping meat onto the bottom portion of lower leg bone so it resembles a lollipop ; reserve legs, thigh bones, and backs separately.
