CC Ādi 17.88
āmra-mahotsava prabhu kare dine dine
In this way the Lord performed saṅkīrtana every day, and at the end of saṅkīrtana there was a mango-eating festival every day for twelve months.
On principle, Lord Caitanya Mahāprabhu would distribute prasādam at the end of kīrtana performances. Similarly, the members of the Kṛṣṇa consciousness movement must distribute some prasādam to the audience after performing kīrtana.
