Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Adds the sharp acidity that gives the dressing its tang.
- Flour
- Thickens the dressing and gives it body as it cooks.
- Egg
- Helps thicken the dressing as it heats and adds richness.
- Mustard
- Adds sharp flavour and helps hold the oil and liquids together.
- Oil
- Adds fat that makes the dressing smooth and rich-tasting.
- Cream
- Adds richness and a silky, mellow texture.
The step that matters
Cooking the egg mixture in the double boiler until thick. Egg proteins set gently with indirect, moderate heat, which thickens the dressing. If the heat is too high or the pan is left unattended, the egg can scramble and the dressing will turn grainy. Stirring constantly helps it cook evenly.
