Wash and roughly chop the carrot, no need to peel, and roughly chop the onion.
Peel the ginger with the back of a spoon, roughly chop as well.
If using a hand-held blender/emulsifier, transfer everything into a blending cup, blend till very smooth and everything is well combined.
If using a blender or kitchen processing, transfer everything but the oil in the container first, blend till smooth, then drizzle in the oil as the machine runs.
Store the dressing in an airtight jar or container in the fridge for up to a week, shake well before you use.
