Preparation materials: 20 fresh long beans, appropriate amount of pepper, appropriate amount of salt, and a clean jar.
1, prepare fresh beans (pay attention to tender beans, so that the soaked beans are more refreshing), and wash them with clear water first.
2. Then put the water into the pot, add pepper and salt to boil, and let it cool after boiling.
3. Prepare a sealed jar, put the washed beans into the jar, and then pour the pepper and salt water into it (water is just enough for beans), but don't fill it up, try to occupy 3/4 of the jar space.
4. Finally, seal the jar mouth with clear water and put it in a cool and ventilated place for 4-5 days, and the delicious sour beans will be marinated.
I'm ready.
5. Take it out when eating and cut it into the desired length.
