Rinse the beans in cold water and
place them in a saucepan along with the
onion,
carrot, and
bouquet garni. Cover generously with cold water and
place over high heat. Bring to a boil, reduce heat, cover, and simmer until the beans are tender, about 2 hours. When the beans are cooked, remove the
onion,
carrot, and
bouquet garni and discard. Set the beans aside.
