A complex Piedmontese stew of sweetbreads, cockscomb, and mushrooms in Marsala wine is old-world elegance. This high protein mediterranean dish celebrates nose-to-tail carnivore cooking traditions.
Soak veal sweetbreads in cold water for 2 hours, changing water once, then blanch in simmering water for 4 minutes. Cool and peel membranes thoroughly.
Clean cockscomb by blanching for 3 minutes in boiling water, then carefully trim and scrape away skin and cartilage. Set aside.
Heat olive oil and butter in a heavy skillet over medium-high heat. Add diced onion, carrot, and celery; sauté for 5-6 minutes until vegetables soften and start to caramelize.
Add sweetbreads, cockscomb, and chicken liver to skillet and brown evenly on all sides for 5 minutes, controlling heat to prevent burning.
Add cremini mushrooms, stir well, then deglaze with Marsala wine. Allow alcohol to evaporate for 2 minutes over high heat, then add beef stock.
Reduce heat to low, cover, and simmer stew gently for 45 minutes, stirring occasionally. Season with salt and black pepper halfway through.
Remove lid and simmer for an extra 10 minutes to concentrate flavors. Taste and adjust seasoning if needed before serving hot.
