Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Provides the main meaty body and fat that keep the loaf juicy.
- Ground pork
- Adds fat and tenderness, so the loaf is less dry than all-beef.
- Fine dry bread crumbs
- Absorb liquid and help the loaf hold together with a tender texture.
- Eggs
- Bind the mixture so it sets into a sliceable loaf when baked.
- Milk
- Adds moisture that softens the crumbs and keeps the meat tender.
- Parmesan cheese
- Contributes savory, salty flavor and some binding through its melted proteins.
The step that matters
Moistening and packing the mixture. Adding the eggs and milk gently and packing lightly keeps the loaf tender. Overworking ground meat develops proteins that toughen it, and too much packing makes a dense loaf.

Fit is the average pairing score against beef, pork, bread, egg, milk, pepper, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
