Prepare the Cabbage: Chop the cabbage into rough pieces, discarding the tough stem.
Salt the Cabbage: In a large bowl or stock pot, fully dissolve the salt in the water. Once dissolved, immerse the cabbage pieces in the water, using a plate to keep them submerged. Keep the cabbage underwater for two hours.
Mix the Ingredients: In another mixing bowl, mix together all of the other ingredients.
Rinse and Dry the Cabbage: Once the cabbage has been underwater for two hours, remove it, drain it, rinse the salt water off and dry it thoroughly.
Combine the Ingredients: Mix the cabbage with all of the other ingredients together.
Ferment the Kimchi: Spoon the Kimchi into a clean glass jar and cover it firmly. Keeping the jar in a cool dry place, leave it alone for two days.
Check for Fermentation: After a day or two, check the Kimchi. If it is bubbling, it is ready and can be eaten – or stored in the fridge. If not, leave it for another day and check again.
Store the Kimchi: When it’s ready, make sure you store it in the fridge. It's best to eat it within two or three weeks before it becomes too fermented.
