Shared aroma: acetic acid (sour, vinegar).
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
- Its lecithin emulsifies the oil into the beaten yolk, giving the dressing its thick, creamy structure.
- Oil
- Makes up most of the volume and provides the rich, smooth body of the dressing.
- Vinegar or lemon juice
- Adds acidity for a bright, sharp flavour that balances the richness of the oil.
The step that matters
Slowly add the oil while whisking continuously. The yolk can only hold oil as tiny droplets if the oil goes in gradually. Adding it too fast overwhelms the emulsifier, and the mixture can split into a greasy, runny layer instead of thickening.
