To make these bagels into star shapes, use a bench cutter to cut the dough into three even pieces. The pieces should look like rough triangles, which you'll want to cut into 5 pieces for each. So from here, grab the first piece of dough and cut off the tip, this will create another "tip," which you again should cut. This create a bunch of elongated triangle pieces. Grab the longest ends and pinch them together in the center to create a star. This can be a bit confusing, so look to the blog post images for guidance.
After the shaping, you can return to the instructions for boiling.
