Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Bind the cheese and rice mixture so it holds together when cooled and cut.
Rice
Provides the body of the squares, absorbing the broth as it cooks.
Zucchini
Adds moisture and tender texture to the squares.
Parmesan cheese
Adds savory flavour and helps the mixture set and brown lightly.
Mozzarella cheese
Melts over the top and browns during baking.

The step that matters

Cook the rice until the liquid is absorbed. Rice that still holds liquid releases it into the egg mixture during baking, leaving the squares wet and loose. Simmering until tender and dry lets the starch set and the squares hold their shape when cut.
