toyāḍhake palāṃśāni pādaśeṣeṇa tena ca |

kṣīraprasthaṃ pacet kṣīraśeṣeṇādyāt ghṛtānvitam |

ṣaṣṭikānnaṃ sitājyena yogo 'yaṃ śukrakṛt param ||

one pala of each, in one āḍhaka of water, and with that reduced to a quarter, / one prastha of milk should be cooked; with the residue of milk, accompanied by ghee, / one should eat ṣaṣṭika rice with sugar and ghee; this recipe produces semen in the highest degree.
