01 - Combine dried fruit and hot black tea in a bowl. Cover and let soak for at least 1 hour or overnight for optimal plumping.

06 - Pour batter into prepared loaf tin and smooth the top surface evenly.
07 - Bake for 55 to 65 minutes until a skewer inserted into the center comes out clean.
08 - Let cool in tin for 10 minutes, then transfer to a wire rack to cool completely.
