As far as I know, there is NO bread machine on the market that does not
leave a hole in the bottom of the loaf from the mixing blade/paddle.
If you want bread without a hole in the bottom, my suggestion is to use
the machine on the manual/dough cycle, remove the dough, reshape and bake
it in a regular bread pan.
Personally I would rather have fresh bread with a hole in the bottom than
no fresh bread at all. This is not a flame, but I find this a little
baffling -- bread machines are designed for convenience, not cosmetics.
The other thing that baffles me is when people say they don't like bread
machines because they don't like the shape of the loaf.
