Lemon Verbena Oat Slice

Lemon Verbena Oat Slice by New Zealand Herbal Brew

This recipe is based on a ginger crunch recipe where lemon verbena replaces the ground ginger.  Lots of variations can be made to the recipe to suit your taste or what is in your pantry; try adding ½ cup of pistachios to the base, or perhaps ½ cup of pumpkin seeds, dried apricots could also be added in place of the currants – the options are endless.

The lemon verbena adds a complex, lemony-grassy-earthy flavour to the slice which is really delicious.  Use a high-speed blender, coffee grinder or mortar and pestle to powder the lemon verbena.
