Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it a firm, chewy bite.
- Tomatoes
- Provide the main body, acidity and fresh flavour of the sauce.
- Clear soup
- Adds savoury depth and liquid to the sauce.
- Flour
- Thickens the sauce as it cooks, giving it body.
- Butter
- Adds richness and smooths the flour-thickened sauce.
- Parmesan cheese
- Adds salty, savoury flavour and a sharp umami note.
The step that matters
Stirring the butter and flour into the boiling sauce. Flour lumps if added raw or unevenly. Creaming it with butter first and stirring it into hot liquid lets the starch disperse and thicken the sauce smoothly instead of clumping.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, flour, butter, parmesan cheese, pepper):
