Begin by combining starter, water, yeast, and 3 cups of flour, in a stand mixer. Mix for about 3-5 minutes, or until combined.
Add remaining flour and salt. Mix again for 3-5 minutes, or until dough comes together.
Add raisins, honey and cinnamon. Mix additional 2-3 minutes, until well combined.
Cover and set dough aside for 1-2 hours, or until doubled in size.
Punch dough down and remove from bowl. Divide into 8-12 pieces.
Shape each piece into a disk shape and create a hole in the center.
Bring 2+ cups of water to boil in a wide and shallow pan. Add sugar to the boiling water. Boil each bagel for 30 seconds, per side. Move to covered baking tray.
Bake bagels for 18-20 minutes, rotating as needed to ensure even browning.
Allow bagels to cool fully before cutting.
