Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tongue
- Forms the main body of the dish and carries the rich, savory flavor.
- Tomatoes
- Provide acidity and body, forming the base of the sauce.
- Flour
- Thickens the sauce so it clings to the tongue like gravy.
- Stock
- Adds liquid and savory depth to the sauce.
- Onion juice
- Adds aromatic onion flavor to the sauce.
The step that matters
Thickening the sauce with flour. Flour must be cooked in the hot liquid long enough to swell and set smoothly. Adding it to cold liquid or stirring too little can leave lumps or a raw, starchy taste.
