Lahey's recipe in his book My Pizza is only 70% hydration as it calls for 500 grams of flour and 350 grams of water with 1/4 teaspoon of yeast and 2 teaspoons of FINE sea salt. Did you find his recipe 100% hydration because it was published in cups and KAF has a light cup of flour at 4.25 ounces. We found the 96% hydration from his published recipe here: http://www.tastingtable.com/entry_detail/99/Jim_Lahey_reveals_his_recipe_for_no-knead_pizza_dough_.htm And yes, this is based on a 4.25oz of flour per cup. If you scoop your measuring cup into the flour bag, you may wind up with closer to 5oz of flour per cup; in this case, the recipe would be closer to 80% hydration. Thank you for sharing the other recipe! It certainly is much closer to normal percentages. Kim@KAF
