Stir with ice, strain into a double old fashioned glass pre-rinsed with absinthe (or Herbsaint), and garnish with lemon oil from a twist.
Not a Vieux Carré riff per se, but the name worked better than altering the De La Louisiane name somehow.
I had a couple at work who only wanted floral drinks. For their second round, one of them wanted a flowery version of a De La Louisiane. I originally doubled up the rye whiskey (at work we use equal parts with the sweet vermouth and Benedictine but with a 110° rye) and swapped out the sweet vermouth for St. Germain. That swap and adjustment was not only a bit sweet, but a bit too bright. I added in some of the vermouth in the form of Punt e Mes especially given how well it works with elderflower in the Maximilian Affair, and that solidified the combination. For a name, I later dubbed this one the Fleur Carré when I made it at home.
