It's a good idea to wear disposable food gloves when mixing all the ingredients together. It's a very unpleasant experience to have chilli powder on your hands and then touch your eyes or nose even if you have thoroughly washed your hands. Ouch! Try and get Korean disposable gloves as they are of better quality than English ones. If you know a good English brand please let me know.
Store the kimchi in an airtight container at room temperature for a day in summer and 2 or 3 days in winter and then keep it in your fridge for up to 2 months, which makes it taste better during the fermentation process. As kimchi ferments it takes on a slightly sour, tingly on your tongue taste.
