Welcome to another edition of Hua Hin Bites, where we dive deep into the local flavors that make our coastal paradise so delicious. Today, we’re not talking about the famous seafood or sweet mangoes. Instead, we’re shining a spotlight on a humble, yet extraordinary superstar of the Thai vegetable world: ถั่วพู (Thua Phu) – the Winged Bean.

If you’ve strolled through the vibrant Hua Hin Night Market or perused the fresh produce at Chatchai Market, you’ve undoubtedly seen these intriguing, four-angled pods. They might look unusual, but for locals, they are a beloved and versatile ingredient. Let's unravel the secrets of this incredible plant.

What Exactly is a Winged Bean?

Scientifically known as Psophocarpus tetragonolobus, the winged bean is a tropical legume. Its most striking feature is the four frilly, wing-like edges running the length of its pod, which gives it its name. While it's now found across Southeast Asia, it has been a staple in Thai cooking for generations.

But here’s what makes it truly special: the entire plant is edible!

• Pods: The most commonly eaten part, harvested while young and green.
• Leaves: Used similarly to spinach in salads or stir-fries.
• Flowers: A beautiful, edible garnish.
• Tubers: The plant grows protein-rich roots (similar to potatoes) that can be boiled or fried.
• Seeds: Mature seeds can be dried and used like soybeans, even pressed for oil. The seeds of winged beans - used in cooking - Roasting Winged Bean Seeds

It’s a true farm-to-table (or garden-to-wok) wonder!

A Taste of Thuaw Phu: Flavor and Texture

So, what does it taste like? The young pods are crisp, juicy, and have a wonderfully refreshing quality. The flavor is subtly sweet and grassy, often described as a cross between a green bean and asparagus. Its magic lies in its ability to absorb the flavors of the dishes it's cooked in while maintaining a satisfying crunch.

How Thais (and Hua Hin Chefs) Love to Cook Winged Beans

In Thailand, thuaw phu is rarely eaten boiled or plain. It’s all about celebrating its texture. Here are the classic ways you’ll find it in Hua Hin:

1. Yam Thuaw Phu (ยำถั่วพู): This is arguably the most famous preparation. A zesty, spicy salad where blanched winged beans are tossed with a fiery dressing of lime juice, fish sauce, chilies, shallots, toasted coconut, and shrimp. The crunch of the bean against the punchy dressing is a textural and flavor explosion. You must try this at a local eatery.

2. Stir-Fries (ผัด): Sliced winged beans are fantastic in stir-fries. A common and delicious version is Pad Thuaw Phu Sapparot ( Stir-Fried Winged Beans with Pineapple), often featuring shrimp. The sweet and savory sauce clings perfectly to the angled pods.

3. Curries (แกง): While they soften when cooked longer, they add a wonderful substance to Thai curries, particularly Gaeng Som (a sour orange curry) or Gaeng Tai Pla (a spicy southern curry).

4. Raw and Dipped: The simplest way? Eaten raw as a fresh vegetable alongside a fiery Nam Prik (chili dip). The cool, crisp bean is the perfect vehicle for a bold, spicy dip.

Why You Should Seek It Out: The Health Boost

This isn’t just any green bean. The winged bean is a nutritional powerhouse, which is why it's often called a "super vegetable."

• High in Protein: Unusually high for a vegetable, making it a fantastic meat alternative.
• Rich in Vitamins & Minerals: Packed with Vitamin A, C, calcium, and iron.
• Full of Fiber: Great for digestion.
• Low in Calories: A perfect healthy, crunchy snack.

After a day in the Hua Hin sun, a dish with thuaw phu is not just a meal; it’s a nutrient-packed recharge.

Finding and Trying Winged Bean in Hua Hin

You won’t have to look hard! Here’s your guide:

• Markets: Any fresh market, especially Chatchai Market (the oldest in town) will have piles of them. Look for bright green, firm pods without blemishes.
• Local Restaurants: Head to a ร้านอาหารตามสั่ง (Raan Aahaan Dtaam Sàng) – a made-to-order stir-fry shop. Just point at the beans in the glass case and say "Pad Thuaw Phu Kap Kai" (stir-fried winged bean with egg) for a simple, delicious dish.
• Specialty: For the iconic Yam Thuaw Phu, ask at Isaan (Northeastern Thai) restaurants or look for it on the menu at authentic Thai eateries, not just those geared toward tourists.

Pro Tip: If you’re feeling adventurous, buy a bag from the market and try making your own salad at your vacation villa! It’s incredibly easy and fresh.

Grow Your Own in Hua Hin!

Living here or have a garden? Winged beans are remarkably easy to grow in Hua Hin’s tropical climate. They thrive in the heat and humidity. Pick up some seeds from a local garden store, provide a trellis for them to climb, and you’ll have a continuous supply of this delicious, edible plant right at your fingertips.

So, next time you’re in Hua Hin, skip the ordinary and seek out the extraordinary winged bean. It’s more than just a vegetable; it’s a taste of local wisdom, a crunch of health, and a true icon of Thai culinary ingenuity.
