Egg and vinegar barely smell alike, yet cooks put them together in 12,922 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 yolk
- Emulsifies the oil and water so the sauce holds together and thickens.
- Oil
- Provides the fat that, dispersed into droplets, gives mayonnaise its rich, thick body.
- Vinegar
- Adds acidity that brightens flavour and helps stabilise the emulsion.
The step that matters
Adding the oil slowly. Oil must be added drop by drop at first so it disperses into tiny droplets that the egg yolk can coat. Pouring too fast breaks the emulsion, leaving a runny, separated sauce.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
