Can you tell me about the Purandare family and their connection to a story involving eggplants?

The source material mentions Raghuvir Bhaskar Purandare, a devotee from Bandra, who once traveled to Shirdi with his entire family, including his children. According to Chapter 9, on this occasion, another person gave them eggplants with a loving request to prepare two dishes for Sai Baba: a mashed dish called 'bharit' and fried slices called 'kachrya'. The lady of the Purandare family, upon arriving in Shirdi, offered the 'bharit' to Baba. The story then unfolds as Baba specifically asks for the 'kachrya', demonstrating his awareness of the devotee's initial loving wish.
