Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when gently heated, thickening the mixture into a soft, spreadable topping.
- Butter
- Adds richness and fat, helping the mixture stay smooth and glossy as it warms.
- Essence of anchovy
- Contributes a salty, savoury depth that stands out against the eggs.
- Capers
- Add a sharp, briny bite that balances the richness of the eggs and butter.
The step that matters
Continue stirring until the eggs begin to set. Over a gentle heat of boiling water, eggs thicken slowly. Stirring keeps them moving so they set evenly and smoothly. If left still or heated too hard, they can scramble into lumps.
Swap the capers
How well each one fits the dish's main ingredients (butter, egg, pepper, anchovy):
- Parsleyfits better
- Capersthe original
- Nutmegfits about as well
- Tarragonfits less well
Fit is the average pairing score against butter, egg, pepper, anchovy. Candidates are from the same food group and used in at least 100 recipes.
