Why it works: Shallot and vinegar are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,374 recipes. 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.
- Butter
- Adds fat and richness, giving the sauce a smooth, rounded mouthfeel.
- Lean ham or bacon
- Adds savory, salty depth as it cooks slowly into the sauce.
- Shallot
- Adds mild aromatic sweetness that builds flavor during simmering.
The step that matters
Simmer gently until everything is tender. Gentle heat softens the tomatoes and aromatics fully while keeping the liquid from boiling hard, which can break down the sauce and make it cloudy or uneven in texture before it is strained.
Swap the mace
How well each one fits the dish's main ingredients (tomato, shallot, ham, vinegar, butter):
- Capersfits better
- Tarragonfits better
- Thymefits better
- 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.
