Why it works: Truffle and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,900 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Scalloped Sweetbreads a LA Richelieu
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sweetbreads
Cut the sweetbreads into slices.
In a saucepan, stew the sweetbreads with butter and white wine. Season with salt, pepper, and nutmeg, and cook for six minutes.
Assemble and bake
Moisten with thick German sauce, then add truffles and mushrooms.
Fill six scallop shells with the mixture.
Sprinkle breadcrumbs on top and drizzle with clarified butter.
Brown slightly in the oven at 350°F (175°C) for about five minutes.
Serve
Serve on a dish with a folded napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that forms the body of the dish.
- Butter
- Adds richness and carries flavour while the sweetbreads stew gently.
- White wine
- Adds acidity and aroma that brighten the stewed sweetbreads.
- Thick german sauce
- Moistens the mixture and binds it into a creamy, cohesive filling.
- Truffles
- Contribute a strong, earthy aroma that gives the dish its luxurious character.
- Mushrooms
- Add savoury depth and a soft, moist texture to the filling.
The step that matters
Brown slightly in the oven. Sweetbreads and sauce are already cooked, so the oven only needs to colour the breadcrumbs and warm the filling. Too long a bake dries the breadcrumbs and can toughen the meat, so watch for light golden colour.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, white wine, pepper, sauce, truffle, mushroom):
- Thymefits better
- Tarragonfits better
- Parsleyfits better
- Nutmegthe original
Fit is the average pairing score against butter, white wine, pepper, sauce, truffle, mushroom. Candidates are from the same food group and used in at least 100 recipes.
