How to Make It
Rinse the beans and transfer them to a large saucepan. Add the bay leaf and 3 quarts of water and bring to a boil. Simmer over low heat until nearly tender, about 1 1/2 hours. Season the beans with salt and simmer until they are tender, but still hold their shape, about 45 minutes longer.
Meanwhile, bring a small saucepan of water to a boil. Add the onion and blanch for 30 seconds. Drain the onion and transfer to a large bowl. Stir in the vinegar, lemon zest, lemon juice and olive oil.
Drain the beans. Add them to the dressing, season with salt and pepper and toss. Let the beans stand for 30 minutes, stirring occasionally. Just before serving, fold in the parsley and tarragon.
The dressed beans can be refrigerated overnight. Return to room temperature and fold in the herbs before serving.
