Mammachi is Chacko and Ammu's mother and Estha and Rahel's grandmother. She's nearly blind and plays a mean violin. She founded Paradise Pickles and Preserves and built it into a successful business before turning it over to Chacko, who transformed it into, um, a less successful business. Mammachi is sort of your typical cranky old-lady figure – very stubborn and set in her beliefs and habits. Her ideas of how the world works are pretty much set in stone. She is prejudiced against the lower classes, always wants to make herself look important, and hates Margaret Kochamma with a passion.
