To make the dough in a stand mixer: Combine warm water and yeast in the bowl of the mixer and let soften for about 5 minutes. Add flour, milk powder, 1/4 cup white sugar, egg, egg white, and salt. Mix, scraping the dough down occasionally, on low speed using the dough hook for 10 minutes. Add butter, currants, and cinnamon and mix for an additional 5 minutes. Transfer dough to a greased bowl, cover with plastic wrap and a kitchen towel, and allow it to rise until doubled, about 1 hour. Proceed with step 4 of the recipe instructions.
