Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Provides the meat that becomes tender during slow stewing in the tomato sauce.
- Butter
- Fat for frying the garlic and onion, carrying their flavor through the sauce.
- Onion
- Adds sweetness and savory depth as it softens and browns in butter.
- Tomatoes
- Provide acidity, liquid and body that form the base of the sauce.
- Spaghetti
- Carries the sauce and gives the dish its starchy base.
The step that matters
Brown the round steak pieces in the pan.. Browning creates flavorful surface compounds through the Maillard reaction. Pieces that are crowded or wet will steam instead, producing a greyer, blander result.
Swap the clove
How well each one fits the dish's main ingredients (garlic, onion, butter, tomato, pepper, cheese):
- Thymefits better
- Cuminfits better
- Parsleyfits better
- Clovethe original
Fit is the average pairing score against garlic, onion, butter, tomato, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
