Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted with flour to form a roux that thickens the sauce and adds richness.
- Flour
- Thickens the melted butter into a roux, giving the sauce body.
- Stewed and strained tomato
- Provides the main liquid, acidity and tomato flavor of the sauce.
- Scalded cream
- Adds richness and a smooth, creamy texture to the sauce.
- Baking soda
- Stirred into the tomato, it neutralizes some acidity in the sauce.
The step that matters
Stir in the scalded cream until combined. Adding cream to acidic tomato can cause curdling if the mixture is too hot or too acidic. Adding the scalded cream gently and stirring until combined helps keep the sauce smooth.
Swap the tomato

- Leekfits better
