Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the dressing as they set with heat, giving it a smooth, creamy body.
Flour
Stabilises the egg mixture so it thickens evenly and does not curdle easily.
Vinegar
Adds acidity that balances the richness of the bacon fat and egg yolks.
Bacon
Adds savoury flavour and fat to the dressing, carried in the pan drippings.

The step that matters

Stir the egg mixture over heat until thick and smooth. Egg yolks set at moderate heat, and if they get too hot or are stirred too little they can scramble or curdle. Gentle, constant stirring keeps the dressing smooth and evenly thickened.

Swap the mustard

How well each one fits the dish's main ingredients (egg, flour, vinegar, pepper):

  1. Capsicumfits about as well
  2. Shallotfits about as well
  3. Mustardthe original
  4. Cucumberfits about as well

Fit is the average pairing score against egg, flour, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
