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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mashed to a paste, they give the dressing a smooth, rich body.
- Beaten egg
- Cooked gently over heat, it thickens the dressing as it sets.
- Oil or drawn butter
- Adds fat, giving the dressing richness and a smooth texture.
- Vinegar
- Adds acidity that balances the richness and sweetness of the dressing.
- Sugar
- Adds sweetness that rounds out the sharpness of the vinegar and lemon.
The step that matters
Stirring the dressing over boiling water. Eggs thicken as they heat, but too much heat scrambles them into lumps. Stirring constantly over gently boiling water, with the bowl not touching the water, keeps the mixture smooth and lets it thicken evenly.
Swap the lemon
How well each one fits the dish's main ingredients (shrimp, lettuce, egg, butter, mustard, sugar, vinegar):
