In this week’s episode of “Cocktails with a Curator,” Curator Aimee Ng explores the history behind one of the audience favorites at the Frick, Jean-Auguste-Dominique Ingres’s “Comtesse d’Haussonville.” Sometimes referred to as the “poster girl” of The Frick Collection, the subject of this celebrated portrait led a fascinating life, taking piano lessons from Chopin and writing biographies of Lord Byron and the Irish revolutionary Robert Emmet. (She published the books anonymously to avoid a scandal.) This week’s complementary cocktail calls for an ounce of absinthe, an anise-flavored spirit invented in Switzerland, the country of her birth.
