1.17

āvāhane svadhākāre mantrā ūhyā visarjane | annakarmaṇy anūhyāḥ syur āmaśrāddhavidhiḥ smṛtaḥ

At the invocation and at the uttering of "svadhā", mantras are to be adapted (ūhya), and at the dismissal; / in the rites of food, they should not be adapted: [such] is remembered as the rule for the raw-grain śrāddha.

In a śrāddha with uncooked food the mantras are to be adapted for the invitation, the svadhā-call and the dismissal, not for the acts concerning the food: this is the rule.
