The reflector of the world’s biggest radio telescope is nothing more than a dish of chicken wire lining a 1,000-ft.-wide hole in the ground. Above it, three tall thin towers poke toward the sky.

We visited Pav Bhaji and Bhurji Center in Mumbai to find out how this dish is made and see just what it takes to make such big batches. It begins by finely dicing tomatoes, onions, and cilantro.
