The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Its proteins set when heated, giving the dish its main structure and body.
- Bearnaise sauce
- Its rich emulsified butter and egg yolk add fat and a creamy texture.
- Onion puree
- Provides a soft, savoury base that cushions the egg.
- Spinach puree
- Adds a soft, earthy base and moisture beneath the fried egg.
- Tomato sauce
- Adds acidity and moisture that cut through the richness of the egg and sauce.
The step that matters
Poach the egg for 1.5 minutes. Egg whites set at moderate heat while the yolk stays runny, so the timing must be exact. Too long and the yolk firms; too short and the white stays unset and wispy.
Swap the onion
How well each one fits the dish's main ingredients (egg, sauce, spinach, tomato):
- Capsicumfits better
- Asparagusfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against egg, sauce, spinach, tomato. Candidates are from the same food group and used in at least 100 recipes.
