make one's mouth water, to
To make someone long for or desire something; to arouse eager anticipation. The term, which alludes to salivating in anticipation of food, transferred the phenomenon to other human desires early on. Richard Eden used the term in writing of cannibals anticipating their prey (The Decades of the New Worlde, 1555). By 1663, when Samuel Butler used it in Hudibras, the term was purely figurative, as it still is, even when it refers to food.
