The Origin

The Ultimate Wok Test

In Cantonese kitchens, chefs are judged by their 干炒牛河. The dish seems simple — wide rice noodles, beef, bean sprouts — but the execution demands mastery of wok hei (breath of the wok).

The noodles should be slightly charred but not burnt, silky but not greasy, each strand separate but not dry. It's a paradox that only a screaming hot wok and confident technique can solve.

"If you can make perfect beef chow fun at home, you can cook anything."

The Ingredients

The Beef

  • 200gFlank steak, sliced thin against the grain
  • 1 tbspSoy sauce
  • 1 tspCornstarch
  • 1 tspOil
  • ½ tspBaking soda (for tenderness)

The Noodles

  • 400gFresh wide rice noodles (ho fun)Must be fresh, not dried

The Rest

  • 2 cupsBean sprouts
  • 3Scallions, cut in 2-inch pieces
  • 2 tbspDark soy sauce
  • 1 tbspLight soy sauce
  • 4 tbspVegetable oil (total)

The Method

01

Prep

1

Marinate beef with soy sauce, cornstarch, oil, and baking soda. Let sit 15-30 minutes.

2

Gently separate rice noodles. If cold/stuck, microwave briefly or soak in warm water.

Noodle Truth

Room temperature, separated noodles are ESSENTIAL. Cold clumpy noodles break. This is non-negotiable.

02

Wok Time (FAST)

3

Heat wok until SMOKING. Add 2 tbsp oil. Sear beef quickly until 80% done (30 seconds). Remove immediately.

4

Wipe wok if needed. Heat again until smoking. Add 2 tbsp oil.

5

Add noodles in a single layer. DON'T TOUCH for 30 seconds — let them char slightly.

6

Flip/toss gently. Add soy sauces. Toss to coat evenly.

7

Add bean sprouts and scallions. Toss briefly.

8

Return beef. Final toss for 15 seconds. Serve immediately.

Speed is Everything

From first oil to plating: under 3 minutes. If it takes longer, your wok isn't hot enough.

Pro Tips

Home Burner Hack

Cook in smaller batches. Home burners can't handle full wok loads. Half portions = better wok hei.

Char but Don't Burn

There's a fine line. Smoky char = good. Black burnt spots = bitter. Learn the difference.

Velvet the Beef

For silkier beef, blanch in hot oil for 30 seconds instead of searing. Restaurant technique.
