Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clear drawn gravy
- Forms the liquid base of the sauce.
- Fresh butter
- Adds richness and body, helping the sauce feel smooth.
- Mushroom ketchup
- Adds deep savory flavor to the sauce.
- Lemon juice
- Adds acidity that brightens the sauce.
- Made mustard
- Adds sharpness and a bit of pungency.
The step that matters
Rubbing the butter smooth with flour. Flour mixed into butter forms a paste that thickens the liquid without lumps when it is whisked in. Added loose, the flour clumps and the sauce stays grainy.
Swap the lemon
How well each one fits the dish's main ingredients (butter, mushroom, ketchup, mustard, capers, pepper, vinegar):
- Lemonthe original
- Limefits about as well
- Avocadofits less well
- Red currantfits less well
Fit is the average pairing score against butter, mushroom, ketchup, mustard, capers, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
