CC Antya 16.94

‘ei dravye eta svāda kāhāṅ haite āila?
kṛṣṇera adharāmṛta ithe sañcārila’
Word for word: 
ei dravye — in these ingredients; eta — so much; svāda — taste; kāhāṅ — where; haite — from; āila — has come; kṛṣṇera — of Lord Kṛṣṇa; adhara-amṛta — nectar from the lips; ithe — in this; sañcārila — has spread.
Translation: 
Śrī Caitanya Mahāprabhu considered, “Where has such a taste in this prasādam come from? Certainly it is due to its having been touched by the nectar of Kṛṣṇa’s lips.”
