This is my elderly French neighbour's recipe for a refreshing and popular French tisane, she drinks it almost daily as a digestif, using dried lemon verbena and mint leaves in the winter. Tisanes are popular in France, and most salons de thé serve all manner of wonderful natural tisanes and teas, with exotic herbs and spices, as well as fruit and berries. Nearly all French gardens have Lemon Verbena growing, it also grows wild on the hedgerows this far South in France, and it is added to all manner of things in the kitchen - from soups to sauces, and of course it makes a refreshing and easy drink. This can be served warm or chilled with ice. Garnish with fresh lemon verbena leaves.
