Medhātithi’s commentary (manubhāṣya):
The use of the term ‘morsel’ implies that the alms are not to consist of fruits and roots only. In fact the present text permits the use of cultivated grains, in the absence of wild ones.

Receiving the alms either ‘in the hollowed hand’—without a dish—or in a piece of broken earthenware, dish, &c.—(28).
