Step 1

Slice the cabbage into 2.5cm strips. Tip into a bowl, mix with 1 tbsp sea salt, then set aside for 1 hr. Meanwhile, make the kimchi paste by blending the garlic, ginger, fish sauce (if using), chilli sauce, sugar and rice vinegar together in a small bowl.

Step 2

Rinse the cabbage under cold running water, drain and dry thoroughly. Transfer to a large bowl and toss through the paste, along with the radishes, carrot and spring onions. Serve straight away or pack into a large jar, seal and leave to ferment at room temperature overnight, then chill. Will keep in the fridge for up to 2 weeks - the flavour will improve the longer it's left.
