《仪礼·少牢馈食礼》
主人左手执酒爵，右手接过上佐食呈上的黍稷和切肺，坐下行祭；又祭酒，不起立，尝酒。
主人左执爵，右受佐食，坐祭之，又祭酒，不兴，遂啐酒。
The host holds the wine cup in his left hand, and in his right hand he accepts the millet and other grains and the cut lungs presented by the upper assistant cook, sits down and performs the sacrifice; he again offers the wine, does not rise, and tastes the wine.
