Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide the bulk and rich, earthy flavor of the catsup.
- Vinegar
- Adds acidity, draws flavor out of the walnuts and helps preserve the liquid.
- Garlic
- Adds sharp, pungent aroma to the liquid.
- Cloves
- Add warm, aromatic spice flavor.
- Mace
- Adds a warm, delicate aroma.
The step that matters
Stir the walnut and vinegar mixture daily for a week. Steeping lets the vinegar slowly draw flavor and color out of the walnuts. Stirring each day keeps the walnut pieces in contact with the vinegar so the extraction is even rather than uneven.
Swap the mace
How well each one fits the dish's main ingredients (walnut, vinegar, clove, garlic):
- Allspicefits better
- Tarragonfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against walnut, vinegar, clove, garlic. Candidates are from the same food group and used in at least 100 recipes.
