Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mash into the oil to form a rich, creamy base for the dressing.
- Raw egg
- Beaten in to add body and help bind the dressing together.
- Salad oil
- Provides fat and smooth richness that carries the dressing's flavour.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness.
- Calf's sweet-bread
- Main protein; boiled until tender, then cut and folded into the dressing.
- Lettuce
- Forms the crisp, fresh bulk of the salad layers.
The step that matters
Boil the sweet-bread until tender. Sweetbreads must be cooked through until tender; underdone they stay rubbery, and the dressing will not soften them. Cutting after cooking keeps the pieces neat.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, pepper, sugar, mustard, vinegar, bread):
- Capsicumfits better
- Horseradishfits better
- Shallotfits about as well
- Lettucethe original
Fit is the average pairing score against egg, pepper, sugar, mustard, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
