Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and flavor to the base and helps form the roux with the flour.
- Flour
- Thickens the melted butter and milk into a smooth, spoonable sauce.
- Milk
- Forms the liquid body of the sauce, giving it creaminess.
- Cheese
- Provides the main flavor and melts into the sauce to make it rich and thick.
- Cooked rice
- Adds bulk and a soft texture to the mixture.
- Chopped nuts
- Adds crunch and a toasty, nutty flavor against the smooth sauce.
The step that matters
Stir in the cheese until melted. Cheese turns stringy or grainy if it overheats or is added to a boiling sauce. Keeping the heat gentle lets the proteins melt smoothly into the sauce.
Swap the nuts
How well each one fits the dish's main ingredients (butter, flour, milk, cheese, rice, pepper):
- Beansfits better
- Almondfits better
- Walnutfits better
- Nutsthe original
Fit is the average pairing score against butter, flour, milk, cheese, rice, pepper. Candidates are from the same food group and used in at least 100 recipes.
