Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovy paste
- Adds a salty, savory depth that builds the sauce's umami backbone.
- Walnut ketchup
- Contributes concentrated savory, slightly bitter flavor and deep color to the sauce.
- Tomato ketchup
- Adds sweetness, body and savory tomato flavor to the sauce.
- White wine vinegar
- Provides acidity that preserves the sauce and sharpens its flavors over the long rest.
- Ground cloves
- Provides warm, aromatic spice flavor that deepens during steeping.
The step that matters
Simmering in the water bath. Keeping the jar at a gentle simmer rather than a hard boil heats the mixture evenly and helps the spices and flavors blend without the vinegar evaporating too quickly. The later week-long rest lets the flavors meld further.
Swap the walnut
How well each one fits the dish's main ingredients (clove, anchovy, pepper, ketchup, tomato, white wine, vinegar):
- Beansfits better
- Walnutthe original
