Place 1 C lukewarm water into a large bowl (lukewarm = warm to the touch but not steaming). Stir in 1 tbsp agave syrup. Sprinkle 1 tbsp yeast over the surface of the water,
Let the yeast activate. The yeast will dissolve and foam up. This takes about 5 minutes.
When the surface of the water is covered in foamy looking yeast, sprinkle in ¼ tbsp. of salt and 1 tbsp oil. Add 1 C whole wheat flour and 1 C all-purpose flour.
Stir until a ball of dough forms. Then turn out the dough onto a lightly floured surface (about ¼ C all-purpose flour). Knead until the dough is a smooth consistency. It will be slightly sticky but not wet or mucky in your hands.
Return the ball of dough to the bowl and cover with a damp towel. Let the dough sit to rise for 20 minutes.
While the dough rises, prepare your baking soda bath by mixing 1 L (4 C) of water with 3 tbsp baking soda in a large pot. Get the pot on the stove over medium heat.
Cover 2 baking trays with parchment paper (or silicone baking mats) and preheat the oven to 350 °F.
