Baked 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.

Mix cold rice and stewed tomatoes with spices and onion to create a filling.
Optionally, fry the filling in hot butter or olive oil until heated.
Place the filling in a baking dish and cover with white stock.
Bake in a 350°F (175°C) oven for 30 minutes or until heated through.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
