Based on the text, what was the specific devotional routine Babasaheb Tarkhad followed, and what did he offer as Naivedya?

After his son left for Shirdi, Babasaheb Tarkhad took on the daily devotional duties himself. As described in Chapter 9, he would pray before Sai Baba's painted image, asking that his service be as devoted as his son's and free from mistakes. His routine involved performing this prayerful worship every day after bathing in the early morning. Specifically for the Naivedya, the text states that Babasaheb offered a piece of sugar candy constantly. It also became his habit to consume that offered sugar candy as 'Prasad' when he returned from work and sat for his afternoon meal, a practice he considered a purification of the food.
