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 by setting into a smooth, creamy texture when heated.
- Vinegar
- Adds acidity that sharpens the flavor of the sauce.
- Oil
- Adds fat that gives the sauce a richer mouthfeel.
The step that matters
Thicken the mixture with the yolks of eggs. Egg yolks thicken through gentle heat; if the mixture boils too hard after they are added, the proteins can scramble and turn grainy. Keep the heat low and stir constantly.
Swap the asparagus
How well each one fits the dish's main ingredients (vinegar, pepper, egg):
- Capsicumfits better
- Mustardfits better
- Cucumberfits better
- Asparagusthe original
Fit is the average pairing score against vinegar, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
