I got inspiration for this recipe from from Mario Batali’s The Babbo Cookbook, which has a similar dish using duck livers. I don’t like the texture of liver, but I do like the taste, so the ground-up filling made spicy with red pepper does me fine. My recipe calls for butter as the additional fat – and it works fine — but if you can afford it, use foie gras instead. It’s waaay better. All you need is a small tin of the stuff, available online.
I often do the pasta with chestnut flour, obtainable at specialty shops such as Corti Bros. in Sacramento, or from my friend Scott at Sausage Debauchery, who sells chestnut flour online. If you can’t find it — and it’s really worth looking for — use spelt flour or barley flour. The key is to get an earthy flavor going.
How to serve? Either with the simple sauce below, or as I did in the picture above: In a clear consomme made from my rich duck broth. Either way is wonderful.
1/4 cup olive oil or duck fat
1/2 medium onion, sliced thin
1 1/2 pounds duck livers (use chicken livers if you cannot find duck)
1 cup red wine
1 teaspoon chile flakes
1 tablespoon oregano
1/2 stick of butter, chilled and cut into cubes
Salt and freshly ground black pepper
3 cups all-purpose flour
1 cup chestnut flour
4-5 eggs, lightly beaten
dash of olive oil
3 tablespoons duck fat
4 tablespoons balsamic vinegar (use decent stuff)
minced parsley for garnish
grated parmigiano cheese for garnish
- Make the pasta. Whisk the two flours together in a large bowl until they are combined. Make a well in the center. Pour the beaten eggs and the olive oil in the well, then stir from the center to begin incorporating the flour. Do this until you get big clumps, then switch to kneading it. Once it’s a big ball, knead vigorously for at least 6 minutes. I knead for 8-10.
- Wrap the dough in plastic and let it rest for at least a half-hour; an hour is better.
- Make the filling. In a frying pan, heat the 1/4 cup oil or duck fat. Add the sliced onion and saute over medium heat until it’s soft, about 10 minutes. Turn up the heat to medium-high and add the livers and the chile flakes. Saute until nice and brown.
- Add the red wine, bring to a boil and reduce for 8-10 minutes until it is down to about 4 tablespoons. Add the oregano, then transfer everything into a food processor and buzz until it’s well-chopped but not a smooth puree. Add salt and pepper to taste. Let this cool to room temperature.
- Once the liver mixture is cool, add in the chopped butter and mix well until it is incorporated.
- Make the ravioli. Roll out your pasta dough in a machine or by hand with a rolling pin until it is the thickness you want; I go to No. 6 on my machine, which is an Atlas.
- Place a teaspoon of liver mixture at about 2-inch intervals on your pasta, then fold over the other half of the sheet on top of the filling, working gently to create an even seal with no air bubbles. Alternatively, you could roll another sheet of pasta out and place it on top of the first one. Cut the ravioli into shape with a sharp knife and place on a floured cookie sheet.
- When you are done, you can freeze them individually (you can then bag them up once they are frozen – skip this step and you’ll have a monstrous glob of ravioli in your freezer) or refrigerate them for a day or so.
- Make the dish. Bring a kettle of heavily salted water (it should taste like the ocean) to a boil and boil the ravioli for 2-3 minutes.
- In a frying pan, bring the three tablespoons of duck fat and the 4 tablespoons of vinegar to a boil. Add the ravioli, turn the heat down to medium and shake the pan to coat them. Serve at once, garnished with the cheese and parsley.
