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, earthy flavor and body.
- Butter
- Adds richness and fat, carrying flavor through the sauce.
- Flour
- Thickens the milk into a smooth sauce as it cooks with the fat.
- Milk
- Forms the liquid base of the sauce, which thickens as the starch sets.
The step that matters
Gradually stir in the milk. Adding milk slowly while stirring keeps the flour evenly dispersed, so lumps do not form. Once the starch is hydrated and heated, the sauce thickens smoothly.
Swap the spinach
How well each one fits the dish's main ingredients (butter, flour, pepper, milk):
- Potatofits better
- Capsicumfits better
- Chivefits about as well
- Spinachthe original
Fit is the average pairing score against butter, flour, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
