Open up the cut in each aubergine and push in about 2 tablespoons of the stuffing.
Place the stuffed aubergine in a glass or plastic container that has a tight cover.
Cover the container and put it in a cool but not refrigerated spot for 1 day to mature.
Then serve and refrigerate.
The kimchi is best eaten during the first 3 days if you prefer a light flavor but for more bite, wait until later in the week when the mixture will have fermented.
