In a high-speed blender, combine all ingredients and purée until smooth. If you prefer a thinner dressing, you can add in an extra tablespoon or so of water. You can leave it on the thicker side if you'll be using it as a dip. (This dressing will also thicken slightly when stored in the fridge.)
Miso paste is already quite salty, so taste your dressing and add extra salt if you like. I usually add an extra pinch or so. Store leftovers in an airtight container in the fridge.
