Preheat the oven to 160-180°C (320-356°F).
Grease a cake tin.
In a large saucepan, combine water, sugar, mixed dried fruit, butter, mixed spice, and bicarbonate of soda.
Bring the mixture to a boil and let it simmer for 5 minutes. Stir occasionally.
Allow the boiled mixture to cool down.
Once cooled, gradually add the beaten eggs and self-raising flour.
Mix well until all ingredients are fully combined.
Pour the batter into the prepared greased cake tin.
Place the tin in the preheated oven.
Bake for approximately 1 hour or until a skewer inserted into the center comes out clean.
