Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean ground beef
- Forms the cup structure and provides the savory, browned meat base.
- Eggs
- Bind the meat so the cups hold their shape while baking.
- Cooked rice
- Adds bulk and soaks up the sauce, giving the filling body.
- Mozzarella cheese
- Melts over the filling, adding richness and a stretchy, creamy texture.
The step that matters
Shaping the meat over foil and inverting it. Raw meat must be pressed firmly around the foil so it holds its cup shape. Egg proteins set as the meat bakes and help it hold together. Loosening it fully from the foil before filling prevents tearing.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, rice, egg, mozzarella cheese):
- Tomatofits better
- Asparagusfits better
- Capsicumfits about as well
- Onionthe original
Fit is the average pairing score against beef, rice, egg, mozzarella cheese. Candidates are from the same food group and used in at least 100 recipes.
