How to make sour beans?

It's hot every day in summer, and people are tired after finishing farm work and have no appetite for anything. In order to stimulate appetite, people will soak some pickled vegetables in their own homes, such as pickled cucumbers, pickled lettuce and sour beans. Let me talk about how to make sour beans delicious.

First, prepare a jar or a larger glass bottle, clean it and drain it to make sure there is no raw water or oil in it.

Second, boil a pot of boiling water. Make sure there is no oil in that pot of boiling water. After the water is boiled, add some salt and a little rock sugar. How much salt to put can be dipped in water without oil with clean chopsticks. I feel more salty than usual when cooking. Let the water cool to room temperature.

Third, choose fresh beans, remove the parts with bugs at both ends and in the middle, and then clean them. After cleaning, put it in the sun and let it dry for half a day. It's best to sun the beans soft so that they can be rolled up.

Fourth, after the beans are dried, bend the beans layer by layer in the jar. After writing the code, pour the cold water into the jar, and the water will drown the beans. If the beans have surfaced, consider pressing them underwater in a small clean bowl.

Usually in summer, it takes only 3-4 days for beans to change from green to light yellow. After the beans change color, they can smell a fragrant sour taste. You can take it out and fry it at this time. The sour beans made in this way are crisp and delicious, which is completely different from those bought outside. Because it is naturally fermented, and many sour beans outside are soaked in vinegar, the taste is different. You can try.

Here, I would like to remind you of several key points in making sour beans. First, it must be oil-free; second, it should use cold boiled water; and third, it should be sealed. Otherwise, the soaked things will go bad easily.
