SC - The siege cook challenge.

[Mark Schuldenfrei]

You can go to a building supply store where they sell bricks and get an
almost ready-made oven.  Buy a chimney liner.  It's masonry - rectangular
and open only at the ends.  Comes in various sizes.  Get enough bricks or
whatever to close the ends up.  Works great - gives you a flat botton for
your pans, plenty of space and solid construction so that the ashes don't
fly about very much and you don't have to worry about the top or sides
caving in on your dinner.  And if you rake up the coals around it, you can
use the flat top as a warming shelf while you bake stuff in it.
