Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh cold meat
- Provides the main body and richness, with fat adding juiciness as it cooks.
- Bread soaked in milk
- Adds moisture and a tender texture by keeping the meat from drying out and tightening.
- Egg
- Binds the mixture so it holds together when sliced after baking.
- Onion
- Adds aroma and savoury flavour to the meat.
The step that matters
Combining the meat with the soaked bread and egg. Mixing too little or too much changes the texture. Overworking ground meat makes it dense and firm, while thorough, gentle mixing spreads the binder evenly so the loaf holds together and stays moist.
Swap the onion
How well each one fits the dish's main ingredients (meat, pepper, bread, milk, egg):

- Onionthe original
Fit is the average pairing score against meat, pepper, bread, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
