Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Its lecithin helps oil and water-based liquids bind together into a stable, creamy emulsion.
- Olive oil
- Supplies the fat that gives the dressing its rich body and smooth texture.
- Vinegar or lemon juice
- Adds acidity that sharpens the flavour and balances the richness of the oil.
The step that matters
Adding the olive oil gradually. The yolk can only hold a limited amount of oil at once. Pouring the oil in slowly while beating lets each addition emulsify fully. Adding it too fast can cause the mayonnaise to separate and become oily and runny.
“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.
