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.
Peel the onions.
Boil the onions until tender.
Roll each onion in tissue paper.
Bake the onions for 1 hour in a 350°F (175°C) oven.
Remove the paper and brown the onions.
Serve with drawn butter.
