Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Lamb's Sweetbreads
Ingredients
Directions
Prepare
Blanch the sweetbreads and place them in cold water.
Make the stew
In a stewpan, combine sweetbreads, broth, pepper, salt, button onions, asparagus tops, and mace.
Stir in a bit of butter and flour, then stew for 1 hour.
Finish and serve
In a bowl, beat the yolks of 2 or 3 eggs with cream, parsley, and nutmeg.
After stewing, add the egg mixture to the stew without boiling, stirring constantly to prevent curdling.
Optionally, add young French beans or peas.
Serve garnished with lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, meaty main body of the dish that absorbs the stew flavours.
- Butter
- Adds richness and, with flour, thickens the stew base for a smoother texture.
- Flour
- Thickens the stew liquid when cooked with butter, giving body to the sauce.
- Egg yolks
- Enrich and thicken the finished sauce, giving it a silky, custard-like body.
- Cream
- Adds richness and moisture, softening the sauce and balancing the egg yolks.
- Broth
- Provides the savoury liquid base that the stew cooks in.
The step that matters
Adding the egg mixture. Egg yolks thicken when gently heated but scramble and curdle if they reach boiling point. Removing the stew from heat or keeping it below a simmer, while stirring constantly, keeps the sauce smooth.
Swap the mace
How well each one fits the dish's main ingredients (pepper, onion, asparagus, butter, flour, egg, cream):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against pepper, onion, asparagus, butter, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
