Ravioli with Sweetbreads Filling

Sweetbreads don’t show up on many home cooks’ radars anymore, which is a shame because this classic French-Italian ravioli filling is one of the more elegant things you can stuff into a fresh pasta dough. The filling combines trimmed veal sweetbreads with ground veal shoulder, onion, shallots, garlic, fresh thyme, and a splash of Cognac for depth.

Roasted until firm, then cooled, the filling reads almost like a rustic pâté before it goes into the pasta.

Prepping sweetbreads is an exercise in patience. Soak them in cold water overnight to purge any residual blood, then blanch briefly and plunge into ice water before removing the membrane and connective tissue. Skip this step and the filling tastes off and has a grainy texture.

Grinding everything coarsely (not pureeing) keeps some texture in the filling, so there’s something to bite into.

The oven-roast step is important. Baking the ground mixture at 400°F (200°C) for 20 minutes firms it up, cooks out excess moisture, and concentrates the flavor. Raw-pasted filling leaks and makes soggy ravioli.

This is the filling recipe only, which needs to be combined with fresh pasta dough and a complementary sauce (brown butter and sage is classic).

Pro Tips

• Buy sweetbreads from a reputable butcher, freshness matters more than almost any other protein
• Remove every scrap of membrane, even small bits contract during cooking and make the filling unpleasant
• Cool the filling completely before stuffing pasta, warm filling steams the dough and weakens it
• Taste after baking and before stuffing, this is your last chance to adjust salt and pepper

Variations

• Swap Cognac for Madeira or dry sherry for a different spirit profile
• Add a tablespoon of mascarpone to the filling for a richer, creamier bite
• Serve the finished ravioli in a veal stock reduction with roasted garlic and seared mushrooms
