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.

Swap the onion

How well each one fits the dish's main ingredients (beef, pork, bread, egg, milk, pepper, parmesan cheese):

  1. Tomatofits better
  2. Potatofits better
  3. Capsicumfits better
  4. Onionthe original

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.
