Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Meat Balls with Tomato Sauce
Ingredients
Directions
Make the meatballs
Finely chop the cold meat.
In a bowl, combine the chopped meat, wet bread crumbs, egg, and seasoning and mix the mixture well.
Form the mixture into balls, similar to sausage meat.
Make the tomato sauce
In a pan, fry the onions until brown.
Add the left-over gravy and tomatoes to the pan, and season.
Cook the sauce for about 20 minutes.
Cook and serve
Gently place the meatballs into the sauce and cook for about 30 minutes.
Serve the meatballs on a platter and cover with the tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Forms the body of the meatballs and gives them their main flavor.
- Bread crumbs
- Soak up the milk and help bind the meatballs so they stay moist.
- Egg
- Binds the meat and crumb mixture so the balls hold their shape.
- Onions
- Browning them builds sweetness and savory depth in the sauce.
- Tomatoes
- Provide acidity and the body of the sauce that coats the meatballs.
The step that matters
Gently place the meatballs into the sauce. Raw meatballs are delicate and can break apart if dropped or stirred hard. Lowering them in gently and simmering keeps them intact while the egg and crumbs set.
Swap the onion
How well each one fits the dish's main ingredients (meat, bread, milk, egg, tomato):
