Ingredients: cabbage, salt, sugar, it's that simple. Use cabbage from Taipei's Hope Plaza or organic cabbage from supermarkets. It is true that you wait 21 days for fermentation before opening the sub-packing. Since the sub-packing does not undergo high temperature sterilization and retains the lactic acid bacteria, it can only be refrigerated and delivered in the shortest time. If you want to purchase other products in the Miao Family Kitchen, you need to order separately. It is very good to eat directly, but the flavor will be doubled if you eat it heated. If you want to know simple and delicious recipes, please indicate in the remarks column when ordering.
