I've been using Peter Reinhart's recipe witth pleasantly tasty, chewy results, but they tend to flatten during the boiling. Ruth Levy Beranbaum's behaved similarly but got a lot of oven spring. The latest batch looked really great pre-boiling so it was kind of disappointing. I could go back to RLB's recipe but I recall it was more complicated -- but maybe that's the answer.
The bagel dough may have too much moisture. Bagel dough must be quite stiff, in order for it to maintain it's shape during the boil.
Also, I tend to shape my bagels with lots of tension, to help assure a nice spring when they hit the oven.
Hope this helps. :)
Hi Carl,
Keep the bagels in the cooler until your water is boiling. Don't take them out and allow them to warm up. The flatness sounds like they are getting overproofed.
Boil the bagels for no more than 45 seconds, then immediately place them in a bowl of ice water until they've cooled. Move them to a rack until all the bagels from your batch are boiled and iced, then get them into the oven.
We're home bakers. At least, I am.
Dan DiMuzio set forth good reasons for using the ice water bath during a previous [url=http://www.thefreshloaf.com/node/12037/shaping-bagels-and-bagel-boards#comment-68426][u]discussion[/u][/url] on bagel boards.
I don't work at the speed of light, so I follow the advice of Hamelman and DiMuzio and use the ice bath. It works.
I think moistness may be the problem; I added more flour than the recipe called for, but they still felt like raised doughnuts going into the water.
