Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein, which becomes tender through slow simmering in the sauce.
- Strained tomato
- Forms the sauce base, adding moisture, body, and acidity to the dish.
- Onion
- Softens during slow frying, adding sweetness and savory depth to the sauce.
- Butter
- Carries the onion in the pan and adds richness and flavor to the sauce.
The step that matters
Simmer gently until the beef is tender. High heat makes the proteins in the meat tighten and toughen, while slow, gentle simmering gives connective tissue time to break down, so the beef becomes tender.
