Start by making the bread dough. In the bowl of a mixer, add the heavy cream, milk, egg, sugar, cake flour, bread flour, yeast, and salt (in that order). Using the dough hook attachment, turn on the mixer to “stir.” Let it go for 15 minutes, occasionally stopping the mixer to push the dough together.
After 15 minutes, the dough is ready for proofing. Cover the bowl with a damp towel and place in a warm spot for 1 hour. The dough will grow to 1.5X its original size.
After the bread dough has proofed for an hour, put the dough back in the mixer and stir for another 5 minutes to get rid of air bubbles. Dump the dough on a lightly floured surface and cut into 12 equal pieces.
Roll out each piece into a rough 8x4 inch rectangle. Sprinkle with cinnamon sugar and dot with a few raisins. Roll into a cigar, and cut the cigar in half lengthwise, leaving one end attached (it'll look like a pair of pants). Twist the two pieces together, and then roll the whole thing into a snail shape, tucking the ends underneath the bun. Lay on a baking sheet, cover with a clean kitchen towel, and allow to rise for another hour.
Preheat the oven to 350 degrees F. Brush the risen buns with egg wash and bake for 13-15 minutes. Right after they're baked, brush with simple syrup.
