Why it works: Ketchup and sauce 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 ↓

Directions
Melt the butter in a saucepan over medium heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the rich base of the sauce and carries the other flavours.
- Anchovy liquor
- Adds the salty, savoury depth that defines the sauce.
- Flour
- Thickens the sauce so it clings to the fish.
The step that matters
Stir in the flour and water to thicken. Flour needs to be fully mixed in and brought to a boil so its starch swells and thickens the sauce evenly. Adding it all at once or skipping the boil can leave lumps or a thin, watery sauce.
Swap the walnut
How well each one fits the dish's main ingredients (butter, anchovy, ketchup, mushroom, lemon, pepper, sauce):
- Walnutthe original
- Beansfits about as well
- Chestnutfits about as well
- Sesamefits less well
Fit is the average pairing score against butter, anchovy, ketchup, mushroom, lemon, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
