String Beans

Ingredients

Directions

Snip off the ends of the string beans into small pieces about an inch long, removing the strings.
Boil the string beans in salted water until tender.
Remove the beans with a skimmer and season with butter, salt, and pepper.
Alternatively, drain the beans, return them to the saucepan, add cream or milk, and heat to boiling.
