Pernod is an anise-flavored liqueur from France, which lends a licorice-y flavor to whatever it's added to. It has a particular afffinity with seafood dishes. Classically used in bouillabaisse and oysters Rockefeller, it's also delicious added to mussel-cooking liquid and cream sauces for fish.
First Impression: Star anise and mint – and a host of other herbs (gentian, vervaine, yarrow). Alcohol in background rather than foreground. Sweetish pastis/licorice, star anise smell overall very much in the style of its frère Pernod Pastis (the thujone-free version of Pernod which was used to take the place of its banned brother in 1920, and is still produced today).
Appearance: Brilliantly clear, bright, almost fluorescent green cast to it. On swirling, leaves a thin coat on the glass with a scalloped edge line with droplets forming from it. Louche is good (turns opalescent with some swirls, pools,etc.) and appears to be to historical standards in terms of color and depth (have an Period Pernod Absinthe Ashtray as a color reference).
Taste: Remarkably smooth at full strength. Not overly complex- mint hits you first, with star anise on its heel coating your tongue and a nice wormwood bitter edge to the finish. With a suitable dilution and sweetening it is very pleasantly smooth and seductive.
