Whisk eggs in a medium bowl. Mix in milk and melted butter until well combined.

Sift flour, baking powder, salt, and cinnamon into a large mixing bowl. Stir in sugar, pecans, almonds, citron, currants, cherries, and lemon peel until well combined. Add wet ingredients and stir just enough to blend. Pour batter into a generously greased 8x4-inch loaf pan. Let stand for 20 minutes.

Preheat the oven to 375 degrees F (190 degrees C).

Bake in the center of the preheated oven until a toothpick inserted into the center comes out clean, 60 to 70 minutes. Remove from the oven and turn out onto a wire rack; let cool for 3 hours before slicing.
