Hayom Yom

My father wrote in one of his letters:

According to the glosses of Ashri, [1] when laving the hands for a meal, pour water over each hand three times consecutively; this was the practice of my father (R. Shmuel). He would leave a little water from the third pouring cupped in the palm of his left hand and, with this water, rub his hands together.

Chulin, Chapter 8, Rosh, Section 43, quoting Riva.
