Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that is the main component of the dish.
- Milk
- Gently cooks the sweetbreads and forms the base of the cream sauce.
- Corn flour
- Thickens the milk into a smooth sauce that coats the sweetbreads.
- Onion
- Adds savory aroma to the milk as it simmers.
- Carrot
- Adds gentle sweetness and aroma to the simmering milk.
The step that matters
Thickening the sauce. Corn flour must be whisked smooth in cold milk before adding the hot milk, otherwise it clumps. Starch thickens as it heats, so the sauce needs steady stirring while it cooks to become smooth and glossy.
Swap the onion
How well each one fits the dish's main ingredients (milk, carrot, corn, flour, lemon, parsley):

- Onionthe original
Fit is the average pairing score against milk, carrot, corn, flour, lemon, parsley. Candidates are from the same food group and used in at least 100 recipes.
