Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Anchovy sauce
- Provides salty, savory depth that stands in for oyster sauce's umami.
- Mushroom ketchup
- Adds savory, earthy umami flavor and deep color.
- Milk
- Adds body and mild sweetness, softening the sharper savory notes.
The step that matters
Boil the mixture until thoroughly mixed. Boiling emulsifies the butter into the liquid and drives off raw, harsh notes from the anchovy and mushroom ketchup, so the sauce tastes blended rather than separated or sharp.
Swap the mace
How well each one fits the dish's main ingredients (milk, anchovy, sauce, mushroom, ketchup, butter, pepper):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against milk, anchovy, sauce, mushroom, ketchup, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
