Traditional London Porter Cake

Gently heat Porter beer with butter and brown sugar until melted.

Stir in a large amount of mixed dried fruits and lemon zest; let soak for 15 minutes.

Beat in eggs once the mixture is cool.

Fold in flour and mixed spices.

Pour into a lined cake tin and bake at 150°C for 1.5 to 2 hours.

The stout beer provides a dark color and a moist, deeply malty crumb.

Best made several days before eating.
