Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef or chuck
- Provides the main body and fat that keep the meatballs moist and tender.
- Breadcrumbs
- Absorb moisture and help the meatballs hold their shape.
- Egg
- Binds the mixture together so the meatballs hold their shape.
- Onion
- Adds savory flavor and moisture to the meat mixture.
- Mushroom soup mix
- Adds savory, umami flavor to the meatballs.
- Grape jelly
- Adds sweetness and body to the sauce as it simmers.
The step that matters
Simmering the sauce. Ketchup and grape jelly must simmer together until the jelly fully melts. Heating them gently lets the sugars dissolve and the sauce thicken and become smooth, instead of staying lumpy or too thin.
Swap the onion
How well each one fits the dish's main ingredients (beef, tomato, sauce, mushroom, egg, pepper, ketchup):
- Capsicumfits better
