Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and provides its green color and vegetable flavor.
- Butter
- Adds richness and fat, carrying flavor and giving the sauce a smooth mouthfeel.
- Flour
- Thickens the milk into a smooth sauce as its starch swells with heat.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats with the flour.
- Sugar
- Adds a little sweetness that balances the bitterness of the spinach.
The step that matters
Gradually add the milk. Adding milk slowly while stirring lets the flour disperse evenly, preventing lumps. Smooth, well-thickened sauce depends on this.
Swap the spinach
How well each one fits the dish's main ingredients (butter, flour, sugar, milk):
- Arrowrootfits better
- Sweet potatofits better
- Potatofits better
- Spinachthe original
Fit is the average pairing score against butter, flour, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
