Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 13.6.8

13.6.8

retaḥ somaḥ /

xiii. 7. Then he invokes the sacrificial food; carrying in his right hand the second (portion of the) sacrificial food he in the left holds together, but without allowing to touch, the Hotṛ's bowl and the cup (thinking) ‘The butter is a thunderbolt; Soma is seed; let me not harm seed by the thunderbolt.’ He does not speak the formula of pouring into it, he does not utter benedictions. Having invoked the sacrificial food and having sniffed it he pauses; he eats the second (portion of the) sacrificial food; then having sipped water he eats of the Hotṛ's bowl. The Soma is the highest kind of proper food; verily thus all, having invoked the highest kind of proper food, eat of it.
