Heat up wok and add 1-2 tbsp oil. Swirl wok to cover as much surface area as possible. Add the kuay teow, followed by light and dark soya sauces. Toss to mix sauces and noodles, letting the noodles rest occasionally so that they can acquire a slight char (wok hei). Divide into two serving plates. (Recipe notes 2)
Into the same wok, add remaining oil. Saute garlic and ginger until fragrant. Add meat – prawns, fish cakes and chicken meat – and stirfry until they start to brown at the edges.
Add chicken stock, choy sum and oyster sauce. Cook for 10 minutes or so to let the flavours fully develop.
Add cornstarch solution and spring onions.
Turn off fire and add beaten egg. Stir through so that the egg forms nice strands. (See Recipe Notes 3)
Finally, season with salt, white pepper and sesame oil. Pour gravy over the noodles that you earlier divided into two serving plates. Ready to eat!

Wat Tan Hor - Quick FAQ1. What is wat tan hor?A beloved Malaysian noodle dish featuring wok-charred flat rice noodles topped with a silky, egg-rich gravy loaded with chicken, prawns, and vegetables.2.

Ensure your stock has body and add cornstarch gradually.10. What can I serve with wat tan hor?It’s already a complete one-bowl meal, but you can pair it with cut red chillies in soy sauce, pickled green chillies or a side of blanched greens
