Mix 4 cups of the flour with the yeast, sugar, and salt. Pour in hot water and beat 100 strokes, or 3 minutes with a mixer. Stir in the remaining flour until the dough is no longer sticky. Knead 8 minutes. Place the dough in a greased bowl, and cover with a damp towel. Let rise 15 minutes (yes, 15 minutes).

Punch down. Shape into two round or oblong loaves, and place on a baking sheet. Cut an X or a few slashes 1/2 inch deep on top with a sharp knife. If desired, brush with water and sprinkle with seeds (I chose not to do this because I don't like it when the seeds fall off as you slice the bread - it's really annoying).

Place on the middle shelf of a cold oven. Place a cake pan of hot water on the lowest shelf. Heat the oven to 400 degrees. Bake 40 to 50 minutes until deep golden brown.
