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 ↓
Fish Scallop
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
In a stewpan, combine the fish with walnut ketchup, made mustard, and anchovy sauce.
Mix these ingredients with the cream until well combined.
Heat the mixture gently, ensuring it does not boil.
Bake and serve
Transfer the mixture to a dish or scallop shells.
Cover with bread crumbs and dot with small lumps of butter.
Brown in the oven at 350°F (175°C) for about 15 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the bulk of the filling and gives the dish its main flavour and body.
- Cream
- Adds moisture and richness, giving the filling a soft, smooth texture.
- Bread crumbs
- Form a crisp topping that browns in the oven.
- Butter
- Adds fat that helps the crumb topping brown and become golden.
- Anchovy sauce
- Adds salty, savoury depth that enhances the flavour of the fish.
The step that matters
Heat the mixture gently, ensuring it does not boil. Cream containing dairy proteins can curdle or separate when boiled, leaving the filling grainy instead of smooth. Gentle heat keeps the sauce creamy and evenly textured.
Swap the walnut
How well each one fits the dish's main ingredients (fish, ketchup, mustard, anchovy, sauce, cream, bread):
- Beansfits about as well
- Walnutthe original
- Chestnutfits about as well
- Peasfits less well
Fit is the average pairing score against fish, ketchup, mustard, anchovy, sauce, cream, bread. Candidates are from the same food group and used in at least 100 recipes.
