Why it works: Cream and flour are a kitchen classic. They rank in the top 20% of all ingredient pairs, and 30,481 recipes mention both. Both carry acetaldehyde, which smells pungent, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds richness and fat, giving the sauce a smooth, full body.
- Flour
- Thickens the sauce as its starch swells and sets when cooked with the hot cream.
- Tomato
- Supplies the main flavour, acidity and colour of the sauce.
The step that matters
Cook thoroughly for 10 minutes. The flour's starch must be fully cooked in the hot cream to thicken the sauce and remove the raw, pasty taste of flour. Undercooking leaves the sauce thin and floury.

Fit is the average pairing score against cream, flour. 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).
