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 soak them in cold water for a while.
Make the stew
In a stewpan, combine sweetbreads, broth, pepper, salt, small onions, and mace.
Stir in a bit of butter and flour, then stew for half an hour.
Add boiled asparagus tops to the stew.
Finish
In a bowl, mix beaten eggs with cream, minced parsley, and nutmeg.
Gently stir in the egg mixture without boiling to avoid curdling.
Optionally, add boiled young French beans or peas for color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb sweetbreads
- Provide the tender, delicate meat that forms the body of the stew.
- Eggs
- Set when gently heated, thickening the stew and giving it a smooth, custard-like body.
- Cream
- Adds richness and a silky mouthfeel, softening the flavor of the stew.
- Flour
- Thickens the cooking liquid as it stews with the butter.
- Butter
- Adds fat for richer flavor and helps carry the taste of the seasonings.
- Broth
- Forms the savory liquid base that the sweetbreads and onions cook in.
The step that matters
Gently stir in the egg mixture without boiling. Egg proteins set when heated and can curdle and turn grainy if the stew boils after the eggs are added. Keeping the heat low keeps the sauce smooth.
Swap the mace
How well each one fits the dish's main ingredients (lamb, pepper, onion, butter, flour, egg, cream):
- Parsleyfits better
- Nutmegfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against lamb, pepper, onion, butter, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
