In a bowl, using a wooden spoon, or in a stand mixer fitted with the dough hook, combine the flour, yeast and salt. Add the eggs and the milk mixture and mix vigorously until the dough begins to form. Gradually add the butter, then the raisins and kirsch. Knead the dough for 5 minutes in the stand mixer or on a floured work surface. Form the dough into a ball and place in a lightly oiled bowl. Cover the bowl with a damp cloth and let rest in a warm and humid place for about 10 minutes.
