Having mixed up the food of all kinds and wetted it with water, he should throw it before the Brāhmaṇas who have eaten, scattering it on the ground.—(244)

Medhātithi’s commentary (manubhāṣya):
The term ‘varṇa’ should be taken as standing for kind. Having ‘mixed up’— brought together—the food along with all the various kinds of seasonings—‘having wetted it with water’—‘he should throw it before the Brāhmaṇas who have eaten’—i.e., become fully satisfied; after they have pronounced the words, ‘We are fully satisfied;’ ‘scattering it’—i.e., it should not be thrown at one place, but broken up and scattered;—‘on the ground’—not in any vessel; on the ground also, not on the bare ground, but on Kuśa-grass, as it is going to be laid down in the next verse. Śaṅkha says that the scattering should be done ‘either once or thrice.’—(244)
