That calls for some improvisation! something "tart" & suitably fortified. (Dowson also remarked: 'write, write, write: it is the only endurable employment except when one is fortified with a glass of absinthe’)

Curious if the inventor of this tasty beverage takes his lead from remark by English poet, Ernest Dowson: "Absinthe makes the tart grow fonder": there's truth to both propositions, maybe.
