The pickle is ready to pack in your bento box straight away, but is best after it has been left to marinate overnight. To do this, place a second, clean bowl on top of the pickle mix with a weight inside (e.g. a can of food) and leave in the fridge overnight.
Before using in your bento, cut the pak choi into bite-sized chunks (store leftovers in the fridge).
Toast the seeds in a dry frying pan over a low to medium heat, stirring regularly to ensure they don‘t burn.
When the seeds are very fragrant and starting to tan, 2–4 minutes, tip them to one side of the pan and quickly drizzle the soy sauce and water mixed together over, stirring until they are completely dry, about 1 minute.
Tip onto a plate and leave to cool completely before storing in an airtight jar.
