I have been looking and searching all over the internet about how to preserve/freeze beans. Until I found one that is easy and fast to do. After I picked the beans I washed it with cold water. I then cut both ends with my fingers and you could hear the snap. I then boil the water when it was boiling I put the beans and wait for 4 minutes. After 4 minutes I turn off the fire and immediately I put the beans into the strainer and let the cold water wash the beans. Let it dry after drying put immediately to the ziploc. Do not forget to label your ziploc.
