I made bagels once when I was younger without success. A couple of months ago I decided to give it another go. After a few attempts and a few round bread rolls with holes...I came up with a combination of a couple of recipies that makes a dense chewy bagel that I was looking for. The sponge creates a lot of the small bubbles so that the dough doesn't have to proof for very long, that was my first lesson and why I ended up with bread rolls! I hope you like them too!
