These are generally considered the finest of all beans, and should
be gathered young. Shell them, lay them in a pan of cold water,
and then boil them about two hours, or till they are quite soft.
Drain them well, and add to them some butter and a little pepper.
They are destroyed by the first frost, but can be kept during the
winter, by gathering them on a dry day when full grown but not the
least hard, and putting them in their pods into a keg. Throw some
salt into the bottom of the keg, and cover it with a layer of the
bean-pods; then add more salt, and then another layer of beans,
till the keg is full. Press them down with a heavy weight, cover
the keg closely, and keep it in a cool dry place. Before you use
them, soak the pods all night in cold water; the next day shell
them, and soak the beans till you are ready to boil them.
