CC Madhya 8.305

rādhā-kṛṣṇa-līlā — tāte karpūra-milana
bhāgyavān yei, sei kare āsvādana
Word for word: 
rādhā-kṛṣṇa-līlā — the pastimes of Śrī Rādhā and Kṛṣṇa; tāte — in that composition; karpūra — the camphor; milana — mixture; bhāgyavān — fortunate; yei — one who; sei — that person; kare — does; āsvādana — tasting.
Translation: 
Their meeting is exactly like a mixture of condensed milk and sugar candy. When they talk of the pastimes of Rādhā and Kṛṣṇa, camphor is added. One who tastes this combined preparation is most fortunate.
