My1 revered father-in-law once related:2 “The Baal Shem used to say that distributing lekach on erev Yom Kippur is an ancient custom.3 While doing so the Baal Shem Tov used to say: ‘I am giving you sweet cake — and may G‑d give you a good year!’ My father [the Rebbe Rashab] used to conclude, ‘…a good year, a sweet year.’”

[The Rebbe added individual blessings to some of the chassidim who filed past his door for lekach.4]
