Ingredients
Directions
Make the emulsion
Place the egg yolks in a clean, cold bowl.
Add the salt and stir with a wooden spoon in a cool place or on ice.
Slowly add the salad oil while stirring for about 15 minutes until the mixture resembles thick cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Act as the emulsifier that holds the oil and vinegar together as a thick sauce.
- Salad oil
- Supplies the fat that gives mayonnaise its rich body when whisked into the yolks.
- Tarragon vinegar
- Adds acidity that brightens the flavour and helps stabilise the emulsion.
- Mustard
- Contains natural emulsifiers that help keep the oil and yolk mixture from separating.
The step that matters
Adding the salad oil slowly. Oil must be added a little at a time while stirring so it disperses into tiny droplets held by the egg yolk. Adding it too fast causes the emulsion to break and the mixture to separate into oily liquid.
