Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
To Make Sauce for a Goose
Ingredients
Directions
Stew the apples
Pare, core, and slice some apples.
Put them in a sauce pan with enough water to keep them from burning.
Set over a very slow fire.
Keep closely covered until reduced to a pulp.
Add a lump of butter and sugar to taste, and beat well.
Serve in a china bowl.
Prepare the ducks
Scald and draw your ducks.
Put them in warm water for a few minutes.
Take them out and put them in an earthen pot.
Pour a pint of boiling milk over them.
Let them lie in the milk for two or three hours.
Dredge them well with flour.
Put them in a copper pot of cold water.
Cover and let them boil slowly for twenty minutes.
Make the onion sauce
Boil eight or ten large onions, changing the water two or three times while boiling.
When enough, chop them on a board to keep them a good colour.
Put them in a sauce pan with a quarter of a pound of butter and two spoonfuls of thick cream, and boil a little.
Take the ducks out and smother them with onion sauce.
Pour over the ducks.

Onion and cream share little aroma chemistry, yet 10,827 recipes mention both: they likely 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
- Onions
- Break down into a pulp to form the body and smooth base of the sauce.
- Butter
- Adds richness and a silky texture to the sauce.
- Thick cream
- Adds richness and smoothness, softening the sauce's texture.
- Milk
- Provides liquid and creaminess, softening the flour-dredged ducks as they soak.
The step that matters
Reducing the onions over a very slow fire, covered. Gentle, covered heat lets the onions soften and break down into a pulp without scorching. Too much heat or an uncovered pan can burn the bottom and leave the sauce with a bitter, uneven taste.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (milk, butter, cream):
- Potatobetter flavor fit
- Leekabout as good a flavor fit
- Onionthe original
- Asparagusabout as good a flavor fit
Fit is the average pairing score against milk, butter, cream. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
