Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boiled Meat Balls
Ingredients
Directions
Prepare the meatballs
Cut the round steak into pieces and grind it together with the suet and onion.
Add salt, pepper, egg, and the soaked bread. Mix until firm.
Shape the mixture into balls.
Boil and make gravy
In a pot, add enough water to completely cover the meat balls.
Bring the water to a boil, then add the meat balls.
Boil until most of the water is gone, leaving a little for gravy. Thicken if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Provides the main meaty body and structure of the meatballs.
- Suet
- Adds fat that keeps the meatballs moist and tender as they cook.
- Egg
- Binds the mixture so the meatballs hold their shape.
- Bread
- Soaked bread adds moisture and softness, helping keep the meatballs tender.
The step that matters
Boil until most of the water is gone, leaving a little for gravy. Boiling evaporates water and concentrates the cooking liquid, so stopping at the right point leaves enough liquid for gravy without making it watery. Thickening can help if the liquid stays thin.
Swap the onion
How well each one fits the dish's main ingredients (pepper, egg, bread):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
