Naan is a traditional flatbread made using the dough enriched with ghee (clarified butter) & curd (yogurt) and cooked at a high temperature inside a clay oven called tandoor. Lately, naan dough is prepared just like any other bread dough using leavening agents such as yeast, baking soda, or baking powder and baked like pizza over a hot stone kept inside the oven.
Jerusalem is one of my favorite cookbooks written by Yotam Ottolenghi and Sami Tamimi for their traditional recipes (you may download the e-book here). I could find a number of vegetarian recipes that we, Indians, could very well try without demur owing to the fact that most of the ingredients are easily available here. Incidentally I found an exceptional cake recipe using fenugreek seeds, the commonly used Indian spices, in this book.
