Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce into a smooth, creamy coating as they gently set with the heat.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Port wine
- Adds sweetness and depth of flavour to the sauce.
- Vinegar
- Adds acidity that brightens the rich sauce and balances the sweetness of the port.
- Cold roast beef
- Provides the main protein, which warms through gently in the sauce.
The step that matters
Mix in the egg yolks, port wine, and vinegar, stirring quickly. Egg yolks thicken when heated but can scramble into lumps if they get too hot or sit still. Stirring quickly and keeping the heat gentle spreads the yolks evenly, so the sauce turns smooth and creamy rather than curdled.
Swap the onion
How well each one fits the dish's main ingredients (beef, parsley, butter, pepper, egg, port wine, vinegar):
- Shallotfits better
- Capsicumfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against beef, parsley, butter, pepper, egg, port wine, vinegar. Candidates are from the same food group and used in at least 100 recipes.
