A Common Vegetable with Many Names
The snake bean, a staple in many cuisines around the world, particularly in Southeast Asia, has a host of other names. These alternative monikers often reflect the vegetable's physical characteristics, its origins, or the regional cultures that adopted it. Its long, twisting pods, which can grow significantly longer than a standard green bean, are the reason behind many of these descriptors. Understanding these names is key to finding and identifying this versatile legume in different markets and recipes.
The Name: Yardlong Bean
The term "yardlong bean" is perhaps the most widely recognized alternative to snake bean. This name is a literal description of the vegetable's potential length. However, it's a slight exaggeration, as the pods rarely reach a full yard (three feet) long. The botanical name, sesquipedalis, which means "one-and-a-half-foot-long," is a more accurate measure of the pod's typical length. Despite the slight inaccuracy, the name clearly communicates the bean's most distinctive feature.
The Name: Chinese Long Bean
Originating in Asia and being particularly prominent in Chinese cuisine, the name "Chinese long bean" is used in many English-speaking countries to denote its cultural significance. The vegetable is a common ingredient in stir-fries, noodle dishes, and various other traditional meals, and its name reflects this culinary heritage. It is often found in Asian grocery stores under this name, helping shoppers identify its intended use.
The Name: Asparagus Bean
The name "asparagus bean" is used to describe the vegetable's flavor profile. When cooked, snake beans have a slightly sweet and nutty flavor that can be reminiscent of asparagus, giving it this alternative name. This is particularly true when the beans are harvested young and are at their most tender.
The Name: Long-Podded Cowpea
For those with a deeper understanding of botany, the name "long-podded cowpea" is technically the most accurate. Snake beans are a subspecies of the cowpea (Vigna unguiculata), which also includes black-eyed peas. This name highlights its genetic relationship to other well-known legumes.
Other Regional Names
Beyond these common names, snake beans have several regional identifiers. Some examples include:
- Bora or Bodi: Often used in the Caribbean, particularly in Trinidad and Tobago and Guyana, where it is a staple in many local dishes.
- Kacang Panjang: The name used in Indonesia and Malaysia.
- Sitaw: The Filipino name for the vegetable.
Culinary Uses of Snake Beans
Snake beans are incredibly versatile in the kitchen. Here are a few ways they are typically used:
- Stir-fries: Their firm texture holds up well to high-heat cooking, making them perfect for stir-fry dishes with garlic, chili, and various sauces.
- Curries: In Thai, Indian, and other Southeast Asian cuisines, they are often simmered in curries or soups.
- Pickling: In Sichuan, China, snake beans are famously fermented and pickled to create a tangy, savory ingredient for various dishes.
- Salads: Young, tender pods can be eaten raw, providing a pleasant crunch in salads.
- Side dishes: Sautéed with aromatics like garlic and ginger, they make a delicious and simple side dish.
