Ingredients

potatoes

Directions

The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Mash the potatoes until very soft.
Beat in butter and milk.
Whisk in the whipped egg white until creamy.
Heap the mixture roughly in a neat baking dish.
Bake in a 400°F (200°C) oven until browned.
