Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion, carrot, celery
- Aromatic vegetables that build the savory flavor base of the sauce.
- Butter
- Fat that softens the vegetables and carries their flavor through the sauce.
- Flour
- Thickens the sauce as it cooks and browns.
- Tomatoes
- Main body and acidity of the sauce, cooked down to a smooth base.
- Boiled ham
- Adds a salty, savory meat note to the sauce.
The step that matters
Cooking the flour until browned and thickened. Flour needs enough heat and stirring to cook out its raw taste and thicken evenly; stopping too early leaves a pasty, floury sauce, while lumps form if liquid is not stirred in smoothly.

Fit is the average pairing score against butter, carrot, thyme, celery, parsley, ham, flour. 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).
