Place the tawa (or flat cast iron pan) on the stove on low to medium heat (approx. 120°F to 150°F).
Add ½ cup butter to a small bowl.
Microwave for 30 seconds to 1 minute.
Lightly flour the rolling surface.
Remove one dough ball.
Press down to flatten. Use extra flour if needed.
Roll the dough out using a rolling pin in one direction.
Flip over and roll in the other direction.
Form a circular roti ¼-inch thick.
Brush the tawa or pan with butter.
Place the rolled out roti onto the tawa.
Flip the roti after 15 to 30 seconds (the color of the roti should start darkening and bubbles may form).
Brush the roti with some of the melted butter.
Flip the roti again. Brush this side with more melted butter.
Flip again. Add more butter if it is dry.
Rotate the roti to ensure even cooking. Press on the edges.
Flip again.
Place each dabla on opposite ends of the roti.
Bring the dablas together to smoosh the roti.
Rotate the roti and repeat the smooshing.
Gently tap the top of the roti until it begins to fall apart.
Remove from the heat (the cook time per roti should be 2 to 3 minutes).
Store in an airtight container like a wax-paper lined cooler.
Serve warm.
