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

What each ingredient does

Lettuce
Forms the crisp base that the warm dressing wilts slightly.
Sour cream
Provides creamy body and a tangy richness to the dressing.
Bacon or ham
Adds salty, savory fat that flavors the dressing.
Vinegar
Adds acidity that sharpens the rich dressing.
Egg
Thickens the hot dressing as it cooks, giving it body.

The step that matters

Thicken the mixture with the beaten egg. Egg proteins set when heated, so the dressing thickens only if it is hot enough. Adding the egg to a mixture that is too cool leaves it thin, while overheating can scramble it into lumps. Stir steadily while adding it.

Swap the lettuce
