Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Strained tomatoes
Form the main body and acidic base of the sauce.
Butter
Adds richness and fat, helping the flour blend smoothly into the sauce.
Flour
Thickens the sauce as it cooks with the butter and tomatoes.
Rich milk
Adds creaminess and softens the tomato's sharp acidity.

The step that matters

Adding the milk off the heat. Tomato acid can cause milk proteins to curdle when hot. Removing the pan from the heat before stirring in the warmed milk helps keep the sauce smooth.

Swap the mace

How well each one fits the dish's main ingredients (tomato, onion, butter, flour, milk, pepper):

  1. Garlicfits better
  2. Thymefits better
  3. Parsleyfits better
  4. Macethe original

Fit is the average pairing score against tomato, onion, butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
