Raw: Enjoy them fresh in salads or as a snack. This method preserves their vibrant color and crisp texture.
Blanched: A brief blanching followed by an ice bath will maintain their snap and color, making them perfect for bean salads or side dishes.
Sautéed or Stir-fried: Quickly sautéing them with garlic, shallots, and pancetta brings out their nutty flavor. They also work well in stir-fries.
Pickled: Their size and crispness make them an excellent candidate for pickling.
Shelled Beans: If you let the pods mature on the vine, they can be harvested as shelling beans for use in soups and stews.
