How does Mammachi stand out as an independent resilient woman in the text?

Mammachi was a woman who was always discouraged by her egoistic Entomologist husband. He never supported her and was jealous of her talent and any sort of attention she received. Probably it was so because of the frustration pent up inside his heart for not receiving the deserved fame of his discovery of the moth he wished to be named after him. However, her pickle recipe was a famous one and she was called by the Kottayam Bible Society to make some of her famous banana jam and tender mango pickle for an upcoming fair. It sold quickly and received more orders than she could cope with. Thrilled with her success, Mammachi decided to persist with the pickles and jam and was kept busy for the whole year. Gradually she set up a pickle factory and made a success of it.
