Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Browned in dripping, they build savory sweetness and depth for the sauce.
- Flour
- Stirred into the hot fat and liquid, it thickens the sauce to a coating consistency.
- Tomatoes
- Add acidity and moisture, helping to form the body of the sauce.
- Tinned beef
- Provides the main protein and savory meaty flavor of the dish.
- Macaroni
- Absorbs sauce as it cooks, adding starch and bulk to the finished dish.
- Dripping
- Fat for browning the onions, adding richness and flavor.
The step that matters
Browning the onions. Onions cooked slowly until deeply browned develop sweetness and savory flavor through the Maillard reaction and caramelization. Pale, undercooked onions leave the sauce flat-tasting.
Swap the onion
How well each one fits the dish's main ingredients (flour, tomato, beef, pepper):
- Capsicumfits better
