Why it works: Mustard and vinegar 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 ↓
Sana Mayonnaise—salad for Slaw
Ingredients
Directions
Make the mayonnaise
In a bowl, mix the mustard and sugar until smooth.
Add the cream and vinegar to taste.
In a separate bowl, stir the egg yolks.
Slowly add oil drop by drop while stirring until it thickens.
Once thickened, pour in the oil in a steady stream while stirring continuously.
Add cayenne pepper, salt, and vinegar to taste.
The sauce should be thick like soft butter.
Serve
Serve as a dressing for lettuce, celery, cold poultry, or fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and water-based ingredients, giving the sauce its thick, creamy body.
- Oil
- Provides the fat that, emulsified with the yolks, builds the sauce's thick texture.
- Mustard
- Helps stabilize the emulsion and adds a sharp, savoury flavour.
- Cream
- Adds moisture and richness, softening the sauce's texture.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness of the fat.
The step that matters
Adding the oil. Oil must be added slowly, drop by drop at first, while whisking. Adding it too fast can overwhelm the yolks, so the emulsion breaks and the sauce stays thin or separates.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, cream, vinegar, egg, pepper):
- Capsicumfits about as well
- Mustardthe original
- Horseradishfits about as well
- Spinachfits less well
Fit is the average pairing score against sugar, cream, vinegar, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
