Put a small bowl of green beans, about grab four. Wash, put into the pot, and then watch the water put, like thin on more, usually put 6-7 small bowl of water. More water is better. Anyway, green bean soup water is also very good. At least 40 minutes to cook, until the green beans rotten, burst open, there is an aroma overflow, so it is cooked. In the middle of cooking, you have to watch it and stir it at any time to avoid it getting mushy. If you use a rice cooker to do it, you do not have to worry about the paste pot. Remember: it's best to put icing sugar, so as to make it more refreshing. If you don't have it, white granulated sugar will also work. Cook it before putting down the sugar, and gently stir it well. It is recommended to cool down and put it in the refrigerator to ice it, so that it is better to drink.
