I'm looking for a rounded oval (not loaf pan) loaf of really good Jewish rye bread, seeded, with a chewy crust and that slightly sour rye taste. Where can I find it in the Boston area? I'll buy lots and put it in my freezer, but first I have to find it. I bought some pretty good rye bread at the Acme supermarket in suburban Philadelphia, but I have not found anything here. The breads around here tend toward the Italian and Portuguese, so there's some good scali and sweet bread. But nothing beats good seeded rye.
