Why it works: Lettuce and mustard 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 ↓
Bavarian Salad
Ingredients
Directions
Prepare
Chop the onions exceedingly small.
Make the dressing
In a bowl, beat the egg yolk with the salt, mustard, and salad oil.
Add the vinegar last and mix well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and vinegar so the dressing holds together rather than separating.
- Salad oil
- Provides fat that carries flavour and gives the dressing a smooth, rich body.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the oil and yolk.
- Lettuce
- Forms the crisp base that the warm-tasting dressing is poured over.
- Beet
- Adds sweetness and colour, contrasting with the sharp dressing.
The step that matters
Add the vinegar last and mix well. The yolk and oil must form a stable emulsion before the acid goes in. Adding vinegar too early or mixing too little can break the dressing so it looks thin and separated.
Swap the onion
How well each one fits the dish's main ingredients (lettuce, vinegar, egg, mustard):
- Horseradishfits better
- Cucumberfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against lettuce, vinegar, egg, mustard. Candidates are from the same food group and used in at least 100 recipes.
