French-beans

Ingredients

young tender beans
brine (for cucumbers)
vinegar (boiling hot)

Directions

Soak the fresh beans in brine for two days.
Pour boiling hot vinegar over the beans and cover tightly to retain steam.
Repeat this process every other day until the beans turn green.
Once they are a fine green color, pack them into jars or bottles.
Fill the jars with the same pickle used for cucumbers and seal tightly.
