Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon or pork fat
- Carries flavour and forms the base of the roux-like thickened mixture.
- Flour
- Thickens the dressing when cooked into the hot fat and water.
- Eggs
- Thicken the dressing as they cook and set, giving body.
- Vinegar
- Adds sharp acidity that balances the fat and sweetness.
- Sugar
- Adds sweetness to offset the sharpness of the vinegar and lemon juice.
The step that matters
Adding the beaten eggs to the boiling mixture. Eggs can curdle or scramble if they meet very hot liquid too abruptly. Keeping the mixture in a hot water bath and stirring continuously lets the eggs thicken gently and evenly.
