Directions

Wash the string beans and break off each end, stripping the strong fibers from end to end.
Cut or break the beans into 1-inch lengths.
Cook the beans in enough boiling, slightly salted water to cover for 1 to 2 hours, until very tender.
Ensure the water is nearly absorbed when done.
Add a little milk and butter if cream is not available, let come to a boil, and serve.
