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

What each ingredient does

Sweetbreads
Provide the tender, delicate meat that forms the body of the salad.
Butter
Browns during frying, adding richness and a golden crust to the sweetbreads.
Egg yolks
Emulsify with the oil to thicken the dressing into a smooth, creamy texture.
Olive oil
Forms the fat base of the dressing, giving it body and smoothness when emulsified.
Vinegar
Adds acidity that brightens the dressing and balances the richness of the oil and yolks.

The step that matters

Adding the oil to the dressing. Oil must be added slowly in a fine stream while beating the yolks so it emulsifies. Added too fast, the dressing separates and stays thin and greasy.
