35.1

ataḥ paraṃ śṛṇuṣva tvaṃ varjyāvarjyapratikriyām /
bhojyamannaṃ paryuṣitaṃ snehāktaṃ cirasaṃbhṛtam //

Hear now from me regarding the remedy for what is to be avoided and not avoided: / Food that is stale, [yet] cooked with fat and kept for a long time, may be eaten;

Madālasā spoke:
Next do thou hearken to the remedial measures for things forbidden and permitted. Rice should he eaten that has been kept awhile, mixed with oil, and long stored; and wheat, barley, and butter-milk and preparations thereof unmixed with oil. The hare, the tortoise, the go-sāmp,[1] the porcupine, and the rhinoceros, my son,—these indeed may he eaten; and the domestic pig and fowl should he eschewed. The remains of food at a śrāddha after the pitṛs and gods and other recipients have been satisfied may be eaten at the desire of the brāhmans. A man who eats flesh that has been killed for the purpose of medicine is not defiled.

asnehāścāpi godhūmayavagorasavikriyāḥ /

and also preparations of wheat, barley, and cow's milk made without fat.
