Kimchi is a traditional Korean dish made with salted fermented vegetables. The fermentation process gives kimchi its sour, salty and umami flavours as well as a sharp acidity. By itself, Kimchi is the star of the show, or you can added to soups and hotpots or chopped to be stirred through brown rice on a stir fry.
Gently wash the cabbage and separate its leaves. Keep the small leaves whole and cut the big ones. In a bowl, sprinkle the cabbage with the salt. Leave for at least 1 hour. After about 30 minutes, shake the bowl to mix the salt and make sure it is in contact with all of the cabbage.
Cut the ginger, garlic, onions, chillies and apple in small pieces. Blend with an immersive blender or in a food processor to make a paste. Spread the spice paste over the cabbage and massage it into all the nooks of the leaves.
Transfer to your sterilised jar pushing the leaves down so that the brine/paste covers the leaves completely, with no air holes. Cover with a thin layer of cling film or baking paper to exclude all air. Screw on lid. Let it ferment at room temperature stirring every 2 days for the first week.
Notes
Make sure your glass jar is sterilised. I boil my jars and lids 1 hour before I use them and let them cool down at room temperature. It is very important that your containers, hands and everything that touches your beautiful ingredients are very clean and sterilised. We just want to attract the good bacteria.
