Preheat the oven to 325°F. Generously grease and flour a 12-cup Bundt pan, coating every curve and the center tube.
In a medium bowl, whisk together the flour, baking soda, and salt.
In the bowl of a stand mixer fitted with the paddle attachment, beat the softened butter, sugar, and lemon zest at medium speed for approximately five minutes, until light and fluffy. Scrape down the bowl as needed.
Mix in the finely grated fresh ginger.
Add the eggs one at a time, mixing well after each addition and scraping down the bowl periodically.
Mix in the fresh lemon juice. The mixture may appear slightly curdled, which is normal.
With the mixer on low speed, add the flour mixture in three additions, alternating with the sour cream. Begin and finish with the flour. Mix only until combined.
Toss the chopped candied citrus peel with approximately one tablespoon of the measured flour. Fold it gently into the batter.
Transfer the batter to the prepared Bundt pan and smooth the top. Do not fill the pan more than three-quarters full.
Bake for 50–60 minutes, or until golden and a wooden skewer inserted into the thickest part comes out clean or with a few moist crumbs.
Cool the cake in the pan for 15 minutes. Invert it onto a wire rack and allow it to cool completely.
To make the glaze, place the powdered sugar in a bowl. Whisk in three tablespoons of orange juice. Add more juice one teaspoon at a time until the glaze is thick but pourable.
Spoon the orange glaze over the completely cooled cake. Decorate with orange zest, candied citrus peel, or fresh mint if desired.
