As a seasoned chef with years of experience preparing offal dishes, I recommend starting by soaking the sweetbreads in fresh water for at least 3 hours to ensure tenderness. Place them in a Dutch oven with a bouquet garni and salt, then cover generously with cold water. Bring to a boil and simmer for 10 minutes. Drain and rinse under cold water. Carefully clean, removing any membranes or waste, and slice each lobe into four or five pieces.
Heat 1 tablespoon of olive oil in a sauté pan and brown the sweetbreads on both sides until golden. Remove and set aside. In the same pan, melt the butter with the chopped onions, parsley, and garlic. Deglaze with white wine and broth, add the peeled, seeded, and chopped tomatoes, and simmer for 10 minutes. Splash with cognac, flambé for added depth, and cook another 15 minutes. Return the sweetbreads to the pan to absorb the flavors, then serve. For a thicker sauce, stir in a teaspoon of cornstarch dissolved in cold water at the end.
Chef Hubert's expert tip: Pair this richly spiced dish with a crisp Graves Blanc or a youthful 1973 Vosne-Romanée estate wine for perfect harmony.
