Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parmesan cheese
- Provides savory flavor and salty, umami richness to the filling.
- Butter
- Adds fat and richness, keeping the filling smooth and tender.
- Eggs
- Bind the filling and set when cooked, holding it together inside the pastry.
- Pastry
- Forms the crisp outer shell that encloses the cheese filling.
- Bread crumbs
- Form a crunchy, golden coating that browns during frying.
The step that matters
Sealing the rounds. If the moistened edges are not pressed firmly together, the filling can leak out during frying. Moistening helps the pastry seal.
