Measure all ingredients into a jug or wide mouth jar. Using a stick blender, puree until smooth. If you don’t have a stick blender use a whisk or regular blender.

Taste and season adding a little salt if needed (unlikely with the miso) or some extra vinegar if you prefer it more refreshing. If you like it hot a little more harissa will do the trick. Keep in the fridge for a month or so.
