Mix the whole wheat flour and water together.  Set it in a warm place overnight to soak.  It should be a soft dough.

In the morning, mix in the yeast and sea salt.

Knead the dough for 5 minutes or so until smooth and elastic.  Set in a warm place to rise for 1 - 2 hours.

Preheat the oven to 450ºF.  Divide the dough into 12 equal pieces, then roll each piece into a rope about 1" thick.

Twist it to create a pretzel shape.

Continue with all the pretzels.  Set them on an ungreased baking sheet.

Mix some baking soda and water together.  Brush it on all the pretzels, then sprinkle with sea salt.

Bake for about 10 minutes, until golden brown.
