Flat bagel problem
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.
