Stuffed Peppers

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the filling

Soak the peppers in salt water for 2 hours, then drain.
Crumble the bread crumbs and mix with tomatoes, butter, salt, and pepper.
Fill the drained peppers with the mixture.

Bake

Place the stuffed peppers in a pan with meat stock or water and the remaining butter.
Bake at 350°F (175°C) for 1 hour.

What each ingredient does

Bell peppers: Form the edible shell that holds the filling during baking.
Bread crumbs: Absorb juices and give the filling body so it holds its shape.
Tomatoes: Add moisture and acidity that flavour the filling as it cooks.
Butter: Adds richness and fat that carries flavour and helps browning.
