Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chopped beef
- Provides the main protein and savoury meaty body of the dish.
- Spaghetti
- Releases starch as it cooks, helping thicken the liquid and give body to the dish.
- Tomatoes
- Add acidity and liquid, building the tomato base that the other ingredients simmer in.
- Onions
- Soften during long cooking and add sweetness and aromatic depth to the sauce.
- Red peppers
- Add sweetness, colour and a fresh vegetable flavour that mellows during simmering.
The step that matters
Maintaining the liquid over three hours. Long simmering evaporates water and concentrates flavour, so adding water as needed keeps the dish from drying out or scorching while the beef and spaghetti become tender and the starch thickens the sauce.
