Instructions

Step 1: Prepare the Ingredients

1. Green beans:
   Wash the beans thoroughly, trim both ends, and cut them into 5 cm (2 inch) pieces.

2. Potatoes:
   Peel and cut the potatoes into thin matchstick strips.
   Soak them in cold water for 10 minutes to remove excess starch — this helps keep them crisp during stir-frying.

3. Drain both vegetables well before cooking.

Step 2: Blanch the Green Beans

1. Bring a pot of water to a boil.

2. Add the green beans and blanch for about 2–3 minutes until slightly softened but still bright green.

3. Drain immediately and rinse with cold water to keep their color and texture. Set aside.

Tips for Success

• Crispy texture: Soaking the potatoes removes starch and prevents them from sticking.

• Bright color: Blanching the beans helps keep their green color and tender texture.

• Add variety: You can include a few slices of pork belly or dried tofu for more flavor.

• Wok heat control: Keep the wok hot enough to stir-fry quickly but not burn the garlic.

Flavor Profile

• Savory and aromatic from the soy sauce and garlic.
