Place mixed dried fruit and nuts in a large bowl.

Pour strong brewed tea over the fruit and nuts.

Add packed brown sugar to the bowl and mix well.

Cover the fruit mixture and let it stand overnight at room temperature. This allows the fruit to soak up the tea and sugar.

Preheat oven to 325°F (160°C).

Prepare a 9 x 5 x 3 inch loaf pan with cooking spray or grease to prevent sticking.

Add self-rising flour, milk, beaten egg, orange marmalade, and cinnamon to the soaked fruit mixture.

Stir all ingredients until just combined. Be careful not to overmix.

Pour the batter into the prepared loaf pan.

Bake in the preheated oven for approximately 60 minutes, or until a wooden skewer inserted into the center comes out clean.

Let the cake cool in the pan for 10-15 minutes before transferring it to a wire rack to cool completely.

Slice and serve.
