Pernod is made from the essence of star anise, a tree-growing fruit from North Vietnam and Southern China. The anethol that is extracted from this essential oil is mixed with the distilled essential oils of other herbs and spices. Pernod's secret formula includes mint, added for its cooling and digestive properties, and coriander, for its heady and subtle flavour. Pernod is different from the other anise spirits, as its subtle taste and bouquet come from the distillation of star anise alone. Pastis, on the other hand, is produced by maceration and includes liquorice as a major flavouring agent.
