The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the mixture as it cooks with the milk, giving the dressing body.
- Milk
- Forms the liquid base that the flour thickens into a smooth sauce.
- Butter
- Adds richness and helps blend the dry ingredients into a smooth paste.
- Vinegar
- Adds sharp acidity that brightens the dressing and balances its richness.
- Soft cottage cheese
- Contributes soft, creamy body and a mild tang to the dressing.
- Sour cream
- Adds creamy richness and a tangy flavor, lightened by whipping.
The step that matters
Adding the vinegar. Acid added to hot, thickened milk can make its proteins clump and curdle. Adding the vinegar slowly while stirring spreads the acid evenly so the dressing stays smooth.
Swap the mustard
How well each one fits the dish's main ingredients (flour, butter, milk, vinegar, egg, cottage cheese, cream):
- Chivefits better
- Potatofits better
- Spinachfits about as well
- Mustardthe original
Fit is the average pairing score against flour, butter, milk, vinegar, egg, cottage cheese, cream. Candidates are from the same food group and used in at least 100 recipes.
