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.

Swap the lemon
