Ingredients

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

Prepare the prunes

Boil prunes with port wine, water, and brown sugar until tender.
Stone the prunes and set aside.

Assemble the loaf

Cut bread into round forms or strips and soak in clarified butter.
Line a baking dish with the soaked bread.
Add the prunes and a little marmalade on top.
Cover with another layer of bread.
Tie a piece of buttered paper over the dish.

Bake

Bake for 1 hour at 350°F (175°C).

What each ingredient does

Prunes: Provide the main filling, adding moisture and a rich, sweet fruit flavour.
Port wine: Softens the prunes while they simmer and adds a deep, fruity aroma.
Brown sugar: Adds sweetness and helps the prunes caramelise slightly as they cook.
Clarified butter: Coats the bread, adding richness and helping it brown in the oven.
Bread: Forms the structure of the loaf, holding the filling between its layers.
Marmalade: Adds sweetness and acidity that complements the prunes.
