Step 1

Using a spoon, peel the ginger, then slice it roughly with a sharp knife. Slice the onion into quarters.

Step 2

You will need lemon juice and lemon zest. Using a zester, zest the lemon and juice it. Add everything to the bowl of the food processor.

Step 3

Add soy sauce, rice wine vinegar, and brown sugar to the bowl of the food processor.

Step 4

Blitz the ingredients until you get a runny chunky paste. You don't want it to be a very smooth paste, so take it easy and use the pulse option.
