Why it works: Mushroom and truffle 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 ↓
Sweetbread Timbales
Ingredients
Directions
Prepare
Parboil and chop the sweetbreads.
In a bowl, combine sweetbreads, grated onion, salt, and red pepper.
Soak the bread in cold water, then squeeze dry and mash through a colander.
Mix the sweetbread mixture with the soaked bread, beaten egg yolks, and chopped mushrooms.
Gently fold in the stiffly beaten egg whites.
Fill and bake
Butter small timbale forms and place a few pieces of truffles in each.
Fill the forms with the sweetbread mixture.
Place the forms in a pan of boiling water, cover with another pan, and bake for 30 to 45 minutes.
Serve
Serve with cream sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whole yolks bind the mixture, while whipped whites lighten it and help it set as it bakes.
- Sweetbreads
- Provide the main body and tender texture of the timbales.
- Stale wheat bread
- Soaked and mashed, it adds moisture and softness to the mixture.
- Mushrooms
- Add moisture and earthy flavor to the filling.
- Truffles
- Add a concentrated, aromatic flavor to each timbale.
The step that matters
Gently fold in the stiffly beaten egg whites. Folding gently keeps the air trapped in the whites, so the timbales rise lightly and set with a delicate texture instead of becoming dense.
Swap the onion

Fit is the average pairing score against wheat, bread, mushroom, pepper, egg, truffle. Candidates are from the same food group and used in at least 100 recipes.
