What was the specific daily offering Babasaheb Tarkhad made to Sai Baba, and what was his worship routine?

After his son left for Shirdi, Babasaheb Tarkhad took over the daily worship. Chapter 9 explains that his routine began in the early morning after bathing. He would stand before Sai Baba's painted image and pray for his service to be accepted. The specific Naivedya, or food offering, that Babasaheb offered constantly was a piece of sugar candy. It was also his routine to later consume this 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.
