Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham or bacon
- Provides savory flavor and fat, which the hot drippings carry into the dressing.
- Egg
- Thickens the warm mixture as its proteins set when heated, giving a creamy coating.
- Sour cream
- Adds richness and tang, and softens the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and balances the fat of the meat.
The step that matters
Stir the egg mixture into the hot ham until it thickens. Egg proteins set when heated, so the mixture thickens into a coating. If the heat is too high or stirring is too slow, the egg can scramble into lumps instead of forming a smooth dressing.
Swap the lettuce
How well each one fits the dish's main ingredients (ham, vinegar, egg, cream, pepper):

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