1. In a mixing bowl, combine warm water, sugar, and yeast. Let it sit for 5 minutes until frothy.
2. Add flour, salt, and cinnamon to the yeast mixture. Mix until a dough forms.
3. Knead the dough for about 10 minutes until smooth and elastic. Add raisins and knead until evenly distributed.
4. Place the dough in a greased bowl, cover, and let it rise for 1 hour or until doubled in size.
5. Preheat the oven to 425°F (220°C). Bring a large pot of water to a boil.
6. Punch down the dough and divide it into 8 equal pieces. Shape each piece into a ball and poke a hole in the center to form a bagel shape.
7. Boil each bagel for 1 minute on each side, then place them on a baking sheet.
8. Bake the bagels for 20-25 minutes or until golden brown.
