Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browning in butter builds a savory, sweet base for the sauce.
- Tomatoes
- Provide the main body, moisture and acidity of the sauce.
- Flour
- Thickens the sauce as it cooks, giving it body.
- Butter
- Adds fat and a rich, smooth finish to the sauce.
The step that matters
Simmer for 15 minutes, stirring occasionally. Simmering lets the tomatoes reduce and the flour fully cook and thicken the sauce. Stirring prevents scorching on the bottom of the pan, which would add a burnt taste.
Swap the tomato
How well each one fits the dish's main ingredients (onion, butter, mustard, flour, sugar, sauce, pepper):
