Why it works: Cream and butter 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 ↓
Cream Sauce for a Hare
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the cream and yolks
Heat the cream in a saucepan until just before boiling.
In a separate bowl, whisk the egg yolks.
Gradually add the hot cream to the egg yolks, stirring constantly.
Make the onion roux
In another pan, melt the butter and sauté the onion until soft.
Stir in the flour and salt, cooking for 1–2 minutes.
Finish the sauce
Combine the cream mixture with the onion mixture, stirring until thickened.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and give it a rich, smooth body as they set gently with heat.
- Cream
- Adds richness and moisture, giving the sauce a silky, smooth texture.
- Butter
- Carries the onion flavour and adds fat for a smooth, rich finish.
- All-purpose flour
- Cooked with butter to form a roux that thickens the sauce.
- Onion
- Adds savoury sweetness and aroma as it softens in the butter.
The step that matters
Adding the hot cream to the egg yolks. If hot cream is poured in too fast or not stirred constantly, the yolks can scramble. Adding it gradually and stirring tempers the yolks so the sauce thickens smoothly instead of curdling.
Swap the onion
How well each one fits the dish's main ingredients (cream, egg, butter, flour):
- Leekfits better
- Chivefits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against cream, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
