Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mayonnaise Fish
Ingredients
Directions
Make the dressing
Rub the yolks of four boiled eggs to a smooth paste with salad oil or butter.
Add salt, pepper, mustard and two teaspoonfuls of white sugar to the paste.
Add six tablespoonfuls of vinegar, last of all.
Beat the mixture until light.
Just before pouring it over the fish, stir in lightly the frothed white of a raw egg.
Prepare and serve
Cut a pound or so of cold boiled fish (halibut, rock or cod) into pieces an inch in length, not chopped.
Serve the fish in a glass dish with half the dressing stirred in.
Spread the remaining dressing over the top and lay lettuce leaves from the core of the head around the edges, to be eaten with it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky body of the dish, cut into pieces so it stays intact.
- Eggs
- Yolks form a smooth, rich dressing; the beaten white adds lightness and froth.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the yolks.
- White sugar
- Adds sweetness that rounds out the sharpness of the vinegar.
- Fat pork
- Renders fat that carries flavour into the pot of chowder base.
The step that matters
Stirring in the frothed egg white. Folding the white in lightly, just before serving, keeps its trapped air so the dressing stays light; overmixing collapses the foam and makes it dense.
Swap the mustard

- Asparagusfits less well
Fit is the average pairing score against sugar, vinegar, flour, egg, pork, pepper. Candidates are from the same food group and used in at least 100 recipes.
