Why it works: Green beans and egg work together. They rank in the top 23% of all ingredient pairs, and 48 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green beans
- Provide the main bulk and body once cooked and mashed into a smooth base.
- Cream
- Adds fat and moisture, giving the mash a richer, softer texture.
- Egg yolks
- Enrich the mixture and help it thicken and set when heated.
The step that matters
Boil the mixture in a basin for one hour. Egg yolks thicken when heated but can curdle or turn grainy if they get too hot or boil hard for a long time. Keep the heat gentle and steady so the mixture stays smooth and creamy.
Flavor stand-ins for the spinach
The recipe marks spinach as optional. How well each one fits the dish's main ingredients (green beans, cream, egg, pepper):
- Potatobetter flavor fit
- Asparagusabout as good a flavor fit
- Capsicumabout as good a flavor fit
- Spinachthe original
Fit is the average pairing score against green beans, cream, egg, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
