Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Mayonnaise Dressing
Ingredients
Directions
Make the emulsion
Beat the egg yolks and salt until very light using a silver or wooden spoon, with the bowl set in a pan of ice water.
Add a few drops of oil at a time until the mixture becomes very thick.
Once thick, add the oil more rapidly while beating hard.
Add the vinegar and continue to beat until thick.
Finish and chill
Stir in the lemon juice and whipped cream, if using.
Chill in the refrigerator for a few hours before serving.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Egg yolk lecithin emulsifies the oil and water so the dressing stays thick and smooth.
- Oil
- Forms the fat base that gives the dressing its rich body and creamy texture.
- Vinegar
- Adds acidity that brightens flavour and helps stabilise the emulsion.
- Whipped cream
- Adds air and extra fat, making the finished dressing lighter and softer.
The step that matters
Adding the oil. Oil must be added a few drops at a time at first, while beating constantly. Adding it too fast overwhelms the egg yolks, so the emulsion breaks and the dressing separates into a greasy liquid.
Swap the lemon
How well each one fits the dish's main ingredients (egg, vinegar, cream, butter):
- Strawberryfits better
- Raspberryfits better
- Vanillafits better
- Lemonthe original
Fit is the average pairing score against egg, vinegar, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
