A strong ale brewed for the gossips who attend at the birth of a child, and for those who come to offer to a husband congratulations at the auspicious event. A cheese, called the Ken-no, or groaning cheese, was also made for the occasion. (See KEN-NO.)
Meg Merrilies descended to the kitchen to secure her share of the groaning malt.Sir W. Scott: Guy Mannering, chap. iii.
