01 - Combine dried fruit with hot tea in a medium bowl. Let soak for 30 minutes to plump the fruit, then drain thoroughly.
02 - Preheat oven to 340°F. Grease and line an 8-inch round or loaf cake tin with parchment paper.
03 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, approximately 3 minutes.
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. Stir in lemon zest.
06 - Gently fold dry ingredients into butter mixture until just combined. Do not overmix.
07 - Fold in soaked dried fruit and chopped nuts (if using) until evenly distributed throughout the batter.
08 - Transfer batter to prepared pan, smoothing the top. Bake for 55 to 65 minutes until a skewer inserted in the center comes out clean.
09 - Let cake cool in the pan for 10 minutes before removing to a wire rack. Cool completely before slicing. Serve plain or spread with butter.
