How to Make It
In a small skillet, toast the cumin and coriander seeds over moderately high heat until fragrant, shaking the pan frequently, about 2 minutes. Transfer the spices to a spice grinder and let cool, then grind coarsely.
In a small bowl, mix the warm water with the honey and yeast and let stand until foamy, about 10 minutes. Put the 7 1/2 cups of flour in a large bowl and stir in the chickpeas, spices and salt. Make a well in the center of the flour and add the yeast mixture. Using a wooden spoon, stir the mixture until the dough becomes very stiff.
Scrape the dough out onto a lightly floured work surface and knead until silky and smooth, about 5 minutes, adding more flour as necessary to prevent sticking. Form the dough into a ball and return it to the bowl. Cover with plastic wrap and let stand in a warm spot until doubled in bulk, about 1 hour.
Preheat the oven to 450°. Punch down the dough and divide it into 16 equal pieces. Shape each piece into a round ball and let rest on a lightly floured work surface for 15 minutes.
Roll out each piece of dough to an irregular 6-inch oval. Working quickly, set 4 of the flat breads directly on the rack in the upper third of the oven and bake for about 10 minutes, or until golden and puffed, like pita. Using tongs, transfer the loaves to a rack. Let the oven return to 450° before baking the remaining loaves. Serve warm.
