Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Provides the main flavour and green colour, and its puree gives the soup its body.
- Bechamel sauce
- Adds body and a smooth, thickened texture to the puree.
- Butter
- Adds richness and a silky mouthfeel.
- Cream
- Adds richness and a smoother, softer texture.
The step that matters
Boil the spinach until very green. Brief boiling in salted water sets the chlorophyll bright green. Overcooking turns spinach dull olive and dulls its flavour, so stop once it is just wilted and vivid.
Swap the spinach
How well each one fits the dish's main ingredients (sauce, butter, cream, sugar, pepper):
- Capsicumfits better
- Mustardfits about as well
- Potatofits about as well
- Spinachthe original
Fit is the average pairing score against sauce, butter, cream, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
