Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Zucchini Rice Squares
Ingredients
Directions
Cook the rice
Cook onion in butter until transparent in a 3-quart saucepan over medium heat.
Add zucchini, rice and broth. Bring to a boil, stirring once or twice.
Reduce heat, cover, and simmer 15 minutes, or until rice is tender and liquid is absorbed.
Assemble and bake
Combine Parmesan cheese, parsley, eggs and pepper sauce; add to cooked rice.
Pour into buttered 8- or 9-inch square pan and top with mozzarella cheese.
Bake at 350 degrees for 15 to 20 minutes.
Serve
Cool; cut into 2" squares.

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.
