On the Vaiśvadeva having been finished, if another guest should happen to arrive,—for him also he should provide food to the best of his ability; but he shall not make any offering (out of that food).—(108)

Medhātithi’s commentary (manubhāṣya):
Food cooked for all is referred to here by the term ‘Vaiśvadeva;’ on this being ‘finished’—i.e., all persons having eaten, and the food having been exhausted,—if another guest should arrive, then for him also he shall provide cooked food; but out of this latter food, he shall not make the offering that is made out of food that is cooked in the household.

The oblation into the tire also—and not only the offering—is not to be made (out of this food); because oblations and offerings have been laid down as to be made out of the food cooked in the morning and evening, and not out of the intervening cookings; as is going to be asserted below (in verse 121). So that, if one happens to cook several times during the day, he should not repeat the Vaiśvadeva offering with each cooking.

‘To the best of his ability’—i.e., with elaborate seasonings or otherwise.—(108)
