Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Forms the main body of the loaf and provides savory flavor and richness.
- Bread crumbs
- Absorb moisture and help keep the meat mixture tender rather than dense.
- Cheese
- Melts inside the loaf to add richness and a gooey filling.
- Eggs
- Bind the mixture so it holds together when sliced.
The step that matters
Seal edges and bake at 350 for 45 minutes. Sealing the edges fully encloses the melting cheese so it stays inside rather than leaking into the skillet. Baking at a steady temperature cooks the meat through while the cheese melts evenly.
Swap the onion
How well each one fits the dish's main ingredients (beef, egg, pepper, celery, bread, mustard, ketchup):
- Horseradishfits better
- Capsicumfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against beef, egg, pepper, celery, bread, mustard, ketchup. Candidates are from the same food group and used in at least 100 recipes.
