Rotis fail to puff up due to insufficient moisture in the dough, improper rolling technique, or an inadequately heated tawa (griddle). Ensuring the dough is soft and pliable, rolling evenly, and cooking on a hot tawa are key to achieving perfectly puffed rotis.
Achieving perfectly puffed rotis requires attention to several key factors throughout the preparation process. Here's a breakdown of the common reasons why your rotis might not be puffing up:
Dough Consistency: The dough should be soft, pliable, and well-kneaded. If the dough is too dry, it won't produce enough steam to puff up. Add water gradually while kneading until the dough reaches a smooth and elastic consistency. Let the dough rest for at least 15-20 minutes after kneading. This allows the gluten to relax and the dough to become more manageable.
Rolling Technique: Roll the roti evenly to ensure uniform thickness. Uneven thickness can cause some parts to cook faster than others, preventing proper puffing. Use gentle pressure and rotate the roti as you roll to maintain a circular shape.
Tawa Temperature: The tawa (griddle) must be sufficiently hot. If the tawa is not hot enough, the roti will dry out before it has a chance to puff up. Heat the tawa over medium-high heat until it's hot enough that a drop of water sizzles and evaporates quickly.
Cooking Process: Cook the roti in two stages. First, cook it on the tawa until small bubbles start to appear on the surface. Then, flip it and cook the other side for a shorter time. Finally, transfer the roti directly onto an open flame (or back on the tawa if you prefer) to puff it up completely. The direct heat causes the trapped steam to expand rapidly, resulting in a perfectly puffed roti.
When cooking the roti on the open flame, use tongs to gently rotate it, ensuring even puffing. Avoid pressing down on the roti, as this can prevent it from puffing fully.
