Why exactly did Cholkar give up sugar, and how did this play into his experience at Shirdi?

Cholkar's renunciation of sugar was a personal act of penance. As detailed in Chapter 15, after Baba granted his wish to pass an examination, Cholkar had vowed to visit Shirdi and distribute sugar candy. However, he faced financial troubles that made it impossible for him to make the journey right away. Feeling a delay in fulfilling his promise, Cholkar decided to give up sugar, which he had promised to distribute, as a form of self-discipline and a reminder of his unfulfilled vow. This secret sacrifice became the centerpiece of his experience at Shirdi. When Baba specifically asked for sugary tea to be given to him, it was irrefutable proof that Baba knew his heart, the reason for his vow, the penance during the delay, and had accepted his devotion completely.
