What are Yard-Long Beans?
Also known as Chinese long beans, snake beans, or asparagus beans, yard-long beans are a subspecies of the cowpea, which is the same species as the black-eyed pea. Despite their name, they typically grow to about 1.5 to 2 feet long, not a full yard. These beans are a popular vegetable, especially in Asia and the Caribbean, prized for their subtle, earthy flavor and firm texture. They are a distinct vegetable from the common green bean, and understanding this difference is key to cooking them correctly. Unlike green beans, they become bland and waterlogged if boiled, and truly shine when cooked with oil.
Prepping Your Beans for Cooking
Proper preparation is the first step to enjoying yard-long beans. Follow these simple steps for best results:
- Choose the best beans: Look for thin, firm, bright green pods without any visible bulges, which can indicate the beans are over-mature and tough. Don't be alarmed if they are slightly floppy or wrinkled, as this is common and doesn't affect freshness.
- Wash thoroughly: Rinse the beans under cool water to remove any dirt or debris.
- Trim the ends: Use a knife to trim the dry ends, or simply snap them off.
- Cut to size: The beans are most often cut into 1 to 3-inch pieces for cooking. Keeping the pieces uniform in size ensures they cook evenly.
How to Cook Yard-Long Beans
To achieve the best texture and flavor, avoid simple boiling. Oil-based cooking methods are your best bet. Here are a few popular techniques:
- Stir-frying: This is one of the most common and effective methods. The high heat and oil prevent the beans from becoming waterlogged. For a classic dish, stir-fry cut beans with garlic and chili flakes, adding a splash of soy sauce or fermented shrimp paste for an authentic Chinese or Filipino flavor.
- Sautéing: Similar to stir-frying, sautéing the beans in oil with aromatics like ginger and garlic produces a tender-crisp texture and concentrates their flavor. Sauté until the beans are lightly browned and blistered.
- Adding to stews and curries: Yard-long beans hold up well in simmered dishes, absorbing the flavors of the broth without becoming mushy. This is a common practice in many Southeast Asian cuisines, such as Filipino sinigang or Indonesian curries with coconut milk.
