• 1 1/2 cups ricotta cheese
• 2/3 cup crumbled chevre (soft goat cheese), at room temperature
• 1/2 cup freshly grated Parmesan cheese
• 1/4 cup crumbled blue cheese , such as Gorgonzola, at room temperature
• 3 tablespoons finely chopped fresh parsley
• Salt and freshly ground black pepper
• 2 packages (12-ounces 50 skins each) wonton skins
• 1 large egg , beaten
• 1 quart chicken broth or canned low-sodium broth
• Freshly grated Parmesan cheese , for serving

Mash the ricotta, goat cheese, Parmesan, blue cheese, parsley, salt and pepper with a rubber spatula in a medium bowl until combined.

Dust a parchment-lined baking sheet with cornstarch. Brush the perimeter of a wonton skin with the beaten egg. Place about 1 heaping teaspoon of the filling in the center, and top with another wonton skin. Press firmly to seal the edges. Place on the baking sheet. Repeat with all the skins and filling, separating the layers of ravioli with parchment. (The ravioli can be prepared up to 8 hours ahead, covered with plastic wrap and refrigerated.)

Bring a very large pot of lightly salted water to a boil over high heat. Drop in the ravioli, stirring them occasionally to be sure they aren't sticking. Cook until the ravioli float to the surface, about 4 minutes.

Using a skimmer or wire sieve, scoop out the ravioli and divide them among soup bowls. Spoon about 1/2 cup of the hot soup into each bowl. Serve immediately, with the cheese passed on the side.
