Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and flavour of the sauce once cooked down.
- Milk
- Adds creaminess and moisture to the tomato mixture.
- Flour
- Thickens the liquid into a spoonable sauce as it cooks.
- Butter
- Adds richness and a smooth fat content to the sauce.
- Celery
- Adds a mild, fresh vegetable flavour and some texture.
The step that matters
Thicken the mixture with flour. Flour must be mixed in evenly so it hydrates and swells rather than forming lumps. Cooking it briefly thickens the liquid and removes the raw starch taste.
Swap the tomato
