Norm (nbicomputers), in response to my question in his introduction topic, suggested I start a new topic. The question is: How do you get a crackly crust on a sour rye bread?

The sour rye I bake is based on George Greenstein's formula in "Secrets of a Jewish Baker." The formula below is what I actually made, though. The changes from Greenstein are: 1) I used instant yeast rather than active dry yeast, 2) I used whole rye rather than white rye to feed my rye sour, 3) I used 1T rather than 1/2 T of caraway seeds and 4) I used 2 1/2 tsp rather than 3 tsps of salt.
