Why it works: Garlic and onion match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Mozzarella Meat Balls and Spaghetti
4 platesIngredients
Directions
Make the meatballs
Put the beef, breadcrumbs, garlic, half the parsley, salt & pepper into a bowl.
Add the egg and mix well.
Cut the mozzarella cheese into 16 small cubes.
Make a heaped teaspoonful of beef mixture and form it into a ball around each cube of cheese.
Cook the sauce
Heat the oil in a large covered pan, add the meatballs to the pan, cover and cook until brown on all sides.
Add the onion to the pan, cook for 2 to 3 minutes, then add the tomatoes and juice.
Bring up to a simmering point, cover and cook for 30 minutes.
Uncover the pan and cook for a further 10 minutes to allow the sauce to reduce and thicken slightly.
Serve
While the meatballs are cooking, cook the spaghetti in boiling water until done to your preference.
Drain well and divide among 4 warmed plates.
Divide the sauce among the plates of spaghetti and then sprinkle with the remaining parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean ground beef
- Forms the body of the meatballs and gives them a savoury, meaty flavour when browned.
- Fresh white breadcrumbs
- Absorb moisture and keep the meatballs tender rather than dense.
- Egg
- Binds the beef and breadcrumbs so the meatballs hold their shape.
- Mozzarella cheese
- Melts into a soft, stretchy centre inside each meatball.
- Onion
- Adds sweetness and aromatic depth to the tomato sauce as it softens.
- Tomatoes
- Form the acidic, moist base of the sauce, which reduces and thickens as it cooks.
The step that matters
Brown the meatballs on all sides before adding the tomatoes. Browning builds savoury flavour through the Maillard reaction and helps the meatballs hold their shape, so they are less likely to break apart in the simmering sauce.
