Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- American cheese
- Melts into a soft, spreadable base that carries the flavor of the sandwich.
- Butter
- Adds fat that makes the cheese mixture smooth and easy to spread.
- Dry mustard
- Adds sharp, pungent flavor that balances the richness of the cheese and butter.
- Tarragon vinegar
- Adds acidity and a light herbal note that brightens the rich spread.
The step that matters
Pounding the cheese, butter and mustard until blended. Cold cheese and butter do not combine evenly on their own. Pounding them together until fully blended gives a smooth, uniform spread rather than lumps of cheese in greasy butter.
Swap the tarragon
How well each one fits the dish's main ingredients (cheese, butter, mustard, vinegar, bread):
- Capersfits about as well
- Tarragonthe original
- Thymefits about as well
- Garlicfits less well
Fit is the average pairing score against cheese, butter, mustard, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
