Here's a simple recipe for making a moist fruit cake:

1. Make and soak the dried fruit mix by combining dried fruits of similar size in a glass bowl.
2. Bake the fruit cake in a pre-heated oven at 150°C (300°F).
3. Optional: Mature the cake with liquor/alcohol ¹.

Alternatively, you can also boil the dry fruits with butter, raisins, cranberries, brown sugar, molasses, and water. Then add eggs, vanilla extract, and nuts before baking the boiled fruit cake ².
