Add raisins to a measuring cup or bowl of water. Let sit for 5 minutes. Drain and let cool. Blot dry. 1 ½ cup raisins 1 cup boiling water
In a large bowl, stir together the flour, sugar, yeast and salt. You can do this in a stand mixer with a paddle attachment or in a large bowl with a whisk. 3 ½ - 3 ¾ cups (420-450 g) bread flour (or all-purpose flour) 2 Tablespoons sugar 2 ¼ teaspoons instant yeast 1 ¼ teaspoons salt
Stir in the milk, water, and butter (or oil) until a shaggy dough forms. Stir in raisins. ½ cup (120 ml) milk ¾ cup (180 ml) water 4 Tablespoons (57 g) unsalted butter,
Switching to your dough hook attachment knead dough (start out with the mixer on low until the flour has been incorporated then increase speed to medium until smooth and the dough comes away from the bowl, about 6-8 minutes until a smooth, slightly sticky dough forms and comes away from the sides of the bowl. You can also do this by hand on a lightly floured surface. Knead dough by hand for 8-10 minutes.
Place dough in a lightly greased bowl, turning once to coat. Cover with a clean tea towel or plastic wrap. Allow to rise until doubled in bulk, about 45 minutes to 1 hour.
Punch dough down gently. Remove the dough from the bowl and place onto a lightly floured counter.
Roll out the dough to about a rectangle, about 8 by 20 inches. Then brush the surface with the beaten egg. Sprinkle on the sugar and cinnamon, leaving a 1-inch border at one short edge uncovered. ¼ cup (50 g) granulated sugar 2 teaspoons cinnamon 1 egg white
Starting at the short edge that is covered in filling, roll up tightly into a log. Tuck the ends under and place into an oiled 8 ½”x 4 ½” inch loaf pan, seam side down. Allow to rise for 45 minutes (to 1 hour depending on kitchen temperature) dough should bounce back when touched, and be slightly higher than the pan (about 1 inch higher). Near end of the rising time, preheat the oven to 350°F.
Bake at 350°F (175°C) for 30-40 minutes until golden brown on top and internal temperature reads 190°F. Remove from the oven and cool in the pan for 10 minutes, then remove fraom the pan and cool completely on a wire cooling rack.
