Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the bulk of the dish and provide its sweet, tender body.
- Butter
- Adds richness and fat, carrying flavour and giving the sauce a smooth mouthfeel.
- All-purpose flour
- Cooked into the butter, it thickens the milk into a smooth, creamy sauce.
- Milk
- Forms the liquid base of the sauce, which thickens as it comes to a boil.
The step that matters
Slowly add the milk while stirring constantly until the mixture boils. Adding milk gradually while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly instead of forming lumps.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour, milk, pepper):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peasthe original
Fit is the average pairing score against butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
