Make the white sauce

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

What each ingredient does

Tomatoes
Supply the main body and acidity of the soup once stewed and strained.
Cornstarch
Thickens the hot milk into a smooth white sauce as its starch swells with heat.
Milk
Forms the creamy liquid base of the white sauce.
Butter
Adds fat for a smoother, richer mouthfeel and flavor.

The step that matters

Adding the tomato mixture to the white sauce. Tomatoes are acidic, and acid can curdle hot milk. Letting the soda reaction finish first reduces the acidity, and the mixture should be added gradually and kept from boiling hard to keep it smooth.

  4. Parsleythe original

Fit is the average pairing score against tomato, butter, milk, bread. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
