Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Forms the main body and liquid of the sauce and provides its base flavor.
- Garlic
- Adds a sharp aroma that mellows and sweetens as it simmers.
- Lemon
- Adds brightness and acidity that balances the richness of the tomatoes and butter.
- Butter
- Adds richness and fat, and browning it gives a nutty flavor.
- Flour
- Thickens the sauce as its starch swells in the hot butter and liquid.
The step that matters
Browning the butter and flour. Cooking the butter and flour until just golden gives a nutty flavor and good thickening power. If it burns, the mixture turns bitter and its starch loses much of its thickening ability.

- Clovethe original
Fit is the average pairing score against tomato, garlic, lemon, pepper, butter, 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).
