Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide the savory, salty flavor that forms the base of the sauce.
- Drawn butter
- Adds richness and fat, giving the sauce a smooth, rounded texture.
- Horseradish
- Contributes sharp, pungent heat and aroma.
- Vinegar or olive oil
- Adds acidity or fat, balancing the richness and sharpness of the sauce.
The step that matters
Beat the mixture until it comes to a boil. Heating the butter-based sauce too fast can cause it to separate or scorch. Beating keeps the emulsion smooth and evenly heated as it reaches a boil.
Swap the lemon
How well each one fits the dish's main ingredients (butter, pepper, horseradish, mustard, sugar, vinegar, turmeric):
- Lemonthe original
- Limefits about as well
- Mangofits less well
- Avocadofits less well
Fit is the average pairing score against butter, pepper, horseradish, mustard, sugar, vinegar, turmeric. Candidates are from the same food group and used in at least 100 recipes.
