Escalloped Onions
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.
Peel and boil the onions until tender.
Chop the boiled onions and place them in a baking dish.
Layer the chopped onions with bread crumbs.
Season with butter, pepper, and coarse sea salt.
Moisten thoroughly with milk.
Bake at 350°F (175°C) for about 30 minutes.
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.
