In a large bowl, using a sifter or a strainer, add the ground ginger, cinnamon, cardamom, orange peel, nutmeg, all-purpose flour, barley flour and almond flour (or equal part all-purpose flour if allergic to nuts) and sift together into the bowl. Once sifted, add the minced candied ginger and mix well, until all the pieces are coated in the flour mixture, to prevent clumping. Add the flour mixture to the bowl with the butter mixture and pour in the cool Imperial Stout mixture; fold together using a spatula until just mixed (no flour clumps).
