Pickled Beans
Ingredients
Directions
Remove the strings from the string beans without breaking them.
Soak the beans in a mixture of strong salt and water for 3 to 4 days, keeping them submerged with a board and weight.
After soaking, wash the beans and place them in a preserving kettle with enough hot water to cover them.
Cover the beans with leaves or a cloth to retain steam and cook until they are green.
Drain the beans and pack them into jars.
Pour hot vinegar over the beans, adding your choice of spices and a small piece of alum to each jar.
