Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Truffles Au Jus
Ingredients
Directions
Prepare the truffles
Wash and pick the truffles.
Stew the truffles in good stock with ½ cup red wine.
Drain the truffles and boil them in jus de veau or beef for 15 minutes.
Make the forcemeat
For the forcemeat, scald a slice of veal and cut it into small pieces.
Chop some bacon and suet finely, then remove sinews and skin.
Pound all the meats together and add salt, pepper, nutmeg, shallots, parsley, and moistened bread crumbs.
Bind the mixture with 3 egg yolks to form a forcemeat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Truffles
- Main flavour ingredient, gently stewed and then simmered so they absorb the surrounding liquids.
- Egg yolks
- Bind the forcemeat, helping the mixture hold together when set by heat.
- Bread crumbs
- Absorb moisture and lighten the forcemeat, giving it a softer texture.
The step that matters
Binding the forcemeat with egg yolks. Egg yolks coagulate when heated, so they bind the meat and crumbs into a cohesive mixture. Adding them to a mixture that is too wet or too cold can make the forcemeat loose or uneven.
Swap the nutmeg
How well each one fits the dish's main ingredients (truffle, red wine, beef, pepper, shallot, parsley, bread):
