Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Preheat the oven to 400°F (200°C).
Remove the insides of the tomatoes.

Stuff and bake

In a bowl, mix the bread crumbs, cheese, onion, pepper, and egg.
Stuff the tomatoes with the mixture.
Sprinkle additional bread crumbs on top and add a piece of butter.
Bake for 1 hour.

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

What each ingredient does

Eggs: Binds the filling so it holds together inside the tomatoes.
Bread crumbs: Absorb moisture and give the filling body, with extra crumbs on top for a crisp surface.
Cheese: Melts into the filling, adding richness and savory flavor.
Butter: Adds fat that promotes browning and flavor on the crumb topping.
