Stuffed Peppers

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Remove seeds from the desired number of sweet peppers.
Make a filling with chopped cold meat, bread crumbs, tomatoes, and one small onion, moistened with warm water.
Season the filling with coarse sea salt and butter.
Fill the peppers with the mixture and place them in a shallow pan with a little water.
Bake in a moderate oven at 350°F (175°C) until the peppers are tender.

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.
