01 - Combine mixed dried fruit with hot black tea in a medium bowl. Allow to soak for at least 30 minutes to plump the fruit, then drain thoroughly.
02 - Preheat oven to 340°F. Grease an 8-inch round cake pan or loaf tin and line with parchment paper for easy removal.
03 - Beat softened butter and granulated sugar in a large bowl until the mixture appears pale, light, and fluffy.
04 - Add eggs one at a time, mixing thoroughly after each addition until fully incorporated.
05 - Sift together flour, baking powder, cinnamon, nutmeg, and salt into the butter mixture. Add lemon zest and mix gently until just combined.
06 - Gently fold the drained soaked fruit and optional nuts into the batter until evenly distributed throughout.
07 - Spoon batter into the prepared pan and smooth the top surface with a spatula.
08 - Bake for 55-65 minutes until a wooden skewer inserted into the center emerges clean.
09 - Let cake rest in the pan for 10 minutes, then transfer to a wire rack to cool completely. Slice and serve plain or with butter.
