Mushroom Pie

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.

Preheat the oven to 350°F (175°C).
Grease a pie dish with butter.
Layer mushrooms at the bottom of the dish.
Sprinkle with pepper, coarse sea salt, and a few pieces of butter.
Add a layer of sliced boiled potatoes.
Continue layering mushrooms and potatoes until the dish is heaped.
Cover with short crust pastry and decorate as desired.
Bake for 45 minutes.
