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 ↓
Bacon and Lettuce Salad
Ingredients

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon (in the method)
- Renders fat for cooking and crisps to add savory, salty crunch to the salad.
- White balsamic vinegar
- Provides the acidity that sharpens the dressing and balances the richness of the oil and bacon.
- Extra-virgin olive oil
- Forms the body of the dressing, carrying flavor and coating the lettuce.
- Dijon mustard
- Acts as an emulsifier that helps the oil and vinegar stay combined.
- Boston lettuce
- Forms the leafy base of the salad, providing a tender, cool texture.
The step that matters
Add the oil in a slow stream while whisking. Adding oil slowly while whisking breaks it into tiny droplets that the mustard can hold in suspension, creating a stable emulsion. Dumping it in at once lets the oil separate from the vinegar, leaving a greasy, unevenly dressed salad.
Swap the shallot
How well each one fits the dish's main ingredients (vinegar, mustard, pepper, olive, lettuce):
- Broccolifits better
- Cucumberfits better
- Horseradishfits about as well
- Shallotthe original
Fit is the average pairing score against vinegar, mustard, pepper, olive, lettuce. Candidates are from the same food group and used in at least 100 recipes.
