Why it works: Shallot and vinegar are a kitchen classic. They rank in the top 12% of all ingredient pairs, and 2,374 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, acidity and flavor of the sauce as they break down.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished sauce.
- Lean ham or bacon
- Contributes savory, salty flavor that seasons the sauce from within.
- Shallot
- Adds a mild aromatic sweetness that builds the base flavor.
The step that matters
Simmer gently until everything is tender. Boiling vigorously can break up the solids unevenly and cloud the sauce, while gentle heat lets the tomatoes and aromatics soften fully so that sieving yields a smooth, well-flavored liquid.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (tomato, shallot, ham, vinegar, butter):
- Capersbetter flavor fit
- Tarragonbetter flavor fit
- Thymebetter flavor fit
- Macethe original
Fit is the average pairing score against tomato, shallot, ham, vinegar, butter. 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).
